The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_check.
The conversion was done using the coccinelle script below plus some

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.
Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.
v3:
* remove out-comented line in drm_gem_framebuffer_helper.h
(Maxime)
v2:
* rename to drm_gem_plane_helper_prepare_fb() (Daniel)

We introduced the BCM2711 support to the vc4 HDMI controller with 5.10,
but this was lacking any of the interrupts of the CEC controller so we
have to deal with the backward compatibility.
Do so by simply ignoring the CEC setup if the DT doesn't have the
interrupts property.

Commit 0a038c1c29 ("drm/vc4: Move LBM creation out of
vc4_plane_mode_set()") changed the LBM allocation logic from first
allocating the LBM memory for the plane to running mode_set,
adding a gap in the LBM, and then running the dlist allocation filling
that gap.
The gap was introduced by incrementing the dlist array index, but was
never checking whether or not we were over the array length, leading
eventually to memory corruptions if we ever crossed this limit.
vc4_dlist_write had that logic though, and was reallocating a larger
dlist array when reaching the end of the buffer. Let's share the logic
between both functions.

LBM base address is measured in units of pixels per cycle.
That is 4 for 2711 (hvs5) and 2 for 2708.
We are wasting 75% of lbm by indexing without the scaling.
But we were also using too high a size for the lbm resulting
in partial corruption (right hand side) of vertically
scaled images, usually at 4K or lower resolutions with more layers.
The physical RAM of LBM on 2711 is 8 * 1920 * 16 * 12-bit
(pixels are stored 12-bits per component regardless of format).
The LBM address indexes work in units of pixels per clock,
so for 4 pixels per clock that means we have 32 * 1920 = 60K

User-space ALSA matches a card's driver name against an internal list of
aliases in order to select the correct configuration for the system.
When the driver name isn't defined, the match is performed against the
card's name.
With the introduction of RPi4 we now have two HDMI ports with two
distinct audio cards. This is reflected in their names, making them
different from previous RPi versions. With this, ALSA ultimately misses
the board's configuration on RPi4.
In order to avoid this, set "card->driver_name" to "vc4-hdmi"
unanimously.

The function vc4_prime_import_sg_table() is an otherwise empty wrapper
around CMA's drm_gem_cma_prime_import_sg_table(). Removing it in favor
of the latter allows to initialize vc4_drm_driver with CMA's initializer
macro.

Moving vc4's mmap code from vc4_mmap() into a GEM object function
allows for the use drm_gem_mmap() and drm_gem_prime_mmap(). The content
of vc4_drm_fpos can then be generated by DEFINE_DRM_GEM_FOPS().
The actual mmap implementation is just a check if the BO is a validated
shader plus the default CMA mmap code.

Use the drm_plane_cleanup() function directly as the drm_plane_funcs
.destroy() handler without creating an unnecessary wrapper around it.

Unlike the previous generations, the HSM clock limitation is way above
what we can reach without scrambling, so let's move the maximum
frequency we support to the maximum clock frequency without scrambling.

The PHY initialisation parameters are not based on the pixel clock but
the TMDS clock rate which can be the pixel clock in the standard case,
but could be adjusted based on some parameters like the bits per color.
Since the TMDS clock rate is stored in our custom connector state
already, let's reuse it from there instead of computing it again.

The pixel rate is for now quite simple to compute, but with more features
(30 and 36 bits output, YUV output, etc.) will depend on a bunch of
connectors properties.
Let's store the rate we have to run the pixel clock at in our custom
connector state, and compute it in atomic_check.

When run with a higher bpc than 8, the clock of the HDMI controller needs
to be adjusted. Let's create a connector state that will be used at
atomic_check and atomic_enable to compute and store the clock rate
associated to the state.

drm_atomic_helper_connector_reset uses kmalloc which, from an API
standpoint, can fail, and thus setting connector->state to NULL.
However, our reset hook then calls drm_atomic_helper_connector_tv_reset
that will access connector->state without checking if it's a valid
pointer or not.
Make sure we don't end up accessing a NULL pointer.
