All drivers add all their connectors so there's no need to keep around an
array of available connectors. Instead we just put the useable (not
writeback) connectors in a temporary array using
drm_client_for_each_connector_iter() everytime we probe the outputs.
Other places where it's necessary to look at the connectors, we just
iterate over them using the same iterator function.
Rename functions which signature is changed since they will be moved to
drm_client in a later patch.

struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so
use that directly instead and attach it as a modeset array onto
drm_client_dev. drm_fb_helper will use this array to store its modesets
which means it will always initialize a drm_client, but it will not
register the client (callbacks) unless it's the generic fbdev emulation.
Code will later be moved to drm_client, so add code there in a new file
drm_client_modeset.c with MIT license to match drm_fb_helper.c.
The modeset connector array size is hardcoded for the cloned case to avoid
having to pass in a value from the driver. A value of 8 is chosen to err
on the safe side. This means that the max connector argument for
drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore,
a todo entry for this is added.
In pan_display_atomic() restore_fbdev_mode_force() is used instead of
restore_fbdev_mode_atomic() because that one will later become internal
to drm_client_modeset.

1. drm_fb_helper->lock

3. drm_client_dev->modeset_mutex

The push-to-system function forces a buffer out of video RAM. This decision
should rather be made by the memory manager. By replacing the function with
calls to the kunmap and unpin functions, the buffer's memory becomes available,
but the buffer remains in VRAM until it's evicted by a pin operation.
This patch replaces the remaining instances of drm_gem_vram_push_to_system()
in ast and mgag200, and removes the function from DRM.

So far, the drm_format_plane_height/width functions were operating on the
format's fourcc and was doing a lookup to retrieve the drm_format_info
structure and return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent.
In order to be extra consistent, also rename that function to
drm_format_info_plane_cpp and to a static function in the header to match
the current policy. The parameters order have also be changed to match the
other functions prototype.

function to drm_format_info_plane_cpp and to a static function in the
header to match the current policy.

drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling
are basically a lookup in the drm_format_info table plus an access to the
hsub and vsub fields of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to these functions is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.
This is amplified by the fact that most of the time the callers will have
to retrieve both the vsub and hsub fields, meaning that they would perform
twice the lookup.

The new interfaces drm_gem_vram_{pin/unpin}_reserved() are variants of the
GEM VRAM pin/unpin functions that do not reserve the BO during validation.
The mgag200 driver requires this behavior for its cursor handling. The
patch also converts the driver to use the new interfaces.

There's now a pointer to struct drm_vram_mm stored in struct drm_device.
DRM drivers that use VRAM MM should use this field to refer to their
instance of the data structure. Appropriate helpers are now provided as
well.
Adding struct drm_vram_mm to struct drm_device further avoids wrappers
and boilerplate code in drivers. This patch implements default functions
for callbacks in struct drm_driver and struct file_operations that use
the struct drm_vram_mm stored in struct drm_device. Drivers that need to
provide their own implementations can still do so.
The patch also adds documentation for the VRAM helper library in general.

The VRAM MM memory manager is a helper library that manages dedicated video
memory of simple framebuffer devices. It is supported to be used with
struct drm_gem_vram_object, but does not depend on it.
The implementation is based on the respective code from ast, bochs, and
mgag200. These drivers share the exact same implementation except for type
names. The helpers are currently build with TTM. This may change in future
revisions.

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.
There are also some rcar-du patches which crossover with media tree
but all should be acked by Mauro.
