v2..v3:

- addressed (some) comments from Daniel Stone, Liviu Dudau, Daniel Vetter
and Brian Starkey - thank you all

In this iteration some rework has been done. The checking logic is now moved
to framebuffer_check() so it is common to all drivers. But the common part
is not good for komeda, so this series is not good for merging yet.
I kindly ask for feedback whether the changes are in the right direction.
I also kindly ask for input on how to accommodate komeda.

The CONFIG_DRM_AFBC option has been eliminated in favour of adding
drm_afbc.c to drm_kms_helper.

v1..v2:

This series adds AFBC support for Rockchip. It is inspired by:

https://chromium.googlesource.com/chromiumos/third_party/kernel/+/refs/heads/factory-gru-9017.B-chromeos-4.4/drivers/gpu/drm/rockchip/rockchip_drm_vop.c

- addressed comments from Daniel Stone, Ayan Halder, Mihail Atanassov
- coding style fixes
