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)
* add tutorial-style documentation

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:
- Improve commit message (Sam)

Rename the macro to DRM_GEM_CMA_DRIVER_OPS_VMAP to align naming with
SHMEM helpers and drm_gem_cma_prime_import_sg_table_vmap(). An variant of
the macro is provided for drivers that override the default .dumb_create
callback. Adapt drivers to the changes.
v3:
* rename macro to signal implicit vmap on imported buffers
v2:
* provide DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE

Allows us to drop the drm_driver.release callback.
This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().
v2: Explain why this cleanup is possible (Laurent).
v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)
I also noticed that I've failed to add the error checking,
__must_check caught that.
