Add tilcdc_crtc_atomic_check(). Checks the display mode validity and
the presence of the mandatory primary plane.
The drm_crtc_helper_funcs mode_fixup() callback is left untouched and
the check function does no try to do its job on purpose, despite what
the mode_fixup() callback's documentations suggests.
The plane's check() callback needs to set drm_crtc_state's
->mode_changed to true if the pixel format for the framebuffer
changes. Because of this drm_mode_config_funcs atomic_check() callback
needs to call drm_atomic_helper_check_modeset() once more after it has
called drm_atomic_helper_check_planes(). If the fixing of the
adjusted_mode would be done in drm_crtc_helper_funcs atomic_check()
callback, it would get over written by the extra
drm_atomic_helper_check_modeset() call.

Add tilcdc_crtc_mode_set_nofb(). The mode_set_nofb() semantics do not
fit well to LCDC, because of the mandatory framebuffer. However, when
the primary plane is required in the check phase, it and the
framebuffer can be found from the atomic state struct.

Add dummy primary plane implementation. LCDC does not really have
planes, only simple framebuffer that is mandatory. This primary plane
implementation has the necessary checks for implementing simple
framebuffer trough DRM plane abstraction. For setting the actual
framebuffer the implementation relies on a CRTC side function.

Make tilcdc_crtc_page_flip() work if crtc is not yet on. The plane
commit sometimes comes before crtc is turned on. The new framebuffer
should be set to scanout also in that case, so that it is there when
crtc is turned on at the end of the commit phase.

Fix tilcdc component master unloading. If a subcomponent module
(tda998x in this case) is unloaded before its master (tilcdc in this
case), it calls drm_put_dev() and it should not be called again by
the master when its module is unloaded. However component_master_del()
must still be called and the check if the drm_put_dev() has been
called must be in component_master_ops unbind() callback, not in
platform_driver remove() callback.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

Since "PCI: Add runtime PM support for PCIe ports", the parent PCIe port
can be runtime-suspended which disables power resources via ACPI. This
is incompatible with DSM, resulting in a GPU device which is still in D3
and locks up the kernel on resume (on a Clevo P651RA, GTX965M).
Mirror the behavior of Windows 8 and newer[1] (as observed via an AMLi
debugger trace) and stop using the DSM functions for D3cold when power
resources are available on the parent PCIe port.
pci_d3cold_disable() is not used because on some machines, the old DSM
method is broken. On a Lenovo T440p (GT 730M) memory and disk corruption
would occur, but that is fixed with this patch[2].

Ensure that the returned set of supported DSM functions (MUX, Optimus)
match the ACPI handle that is set in nouveau_dsm_pci_probe.
As there are no machines with a MUX function on just one PCI device and
an Optimus on another, there should not be a functional impact. This
change however makes this implicit assumption more obvious.

The patch f045f459d9 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses")
tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the
display when using fonts with width that is not divisiable by 8.
The monochrome bitmap for each character is stored in memory by lines from top
to bottom. Each line is padded to a full byte.
For example, for 22x11 font, each line is padded to 16 bits, so each
character is consuming 44 bytes total, that is 11 32-bit words. The patch
f045f459d9 changed the logic to "dsize = ALIGN(image->width *
image->height, 32) >> 5", that is just 8 words - this is incorrect and it
causes display corruption.
This patch adds the necesary padding of lines to 8 bytes.
This patch should be backported to stable kernels where f045f459d9 was
backported.
