Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
maybe a bit too much, hence the num_ioctls assignment prevents a
const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
from me.
- legacy drivers, because legacy requires non-const drm_driver.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else
is way too much).
v2: Fix one misplaced const static, should be static const (0day)
v3:

The i.MX DCSS driver uses CMA helpers with default callback functions.
Initialize the driver structure with the rsp CMA helper macro. The
driver is being converted to use GEM object functions as part of
this change.
Two callbacks, .gem_prime_export and .gem_prime_import, were initialized
to their default implementations, so they are just kept empty now.

When compiling for 32bit platforms, the compilation fails with:
ERROR: modpost: "__aeabi_ldivmod"
[drivers/gpu/drm/imx/dcss/imx-dcss.ko] undefined!
ERROR: modpost: "__aeabi_uldivmod"

This patch adds a dependency on ARM64 since no 32bit SoCs have DCSS, so far.

This adds initial support for iMX8MQ's Display Controller Subsystem (DCSS).
Some of its capabilities include:
* 4K@60fps;
* HDR10;
* one graphics and 2 video pipelines;
* on-the-fly decompression of compressed video and graphics;
The reference manual can be found here:
https://www.nxp.com/webapp/Download?colCode=IMX8MDQLQRM
The current patch adds only basic functionality: one primary plane for
graphics, linear, tiled and super-tiled buffers support (no graphics
decompression yet), no HDR10 and no video planes.
Video planes support and HDR10 will be added in subsequent patches once
per-plane de-gamma/CSC/gamma support is in.
