This patch adds support for afbc handling. afbc is a compressed format
which reduces the necessary memory bandwidth.

Hi Andrzej,

I believe this can still be DRM_FORMAT_MOD_INVALID, which != 0. You
probably want to explicitly check if it's an AFBC modifier.

This can just be a WARN_ONCE() or something, since it indicates an
impossible condition - the DRM core should've already rejected this
modifier as unsupported.

Userspace shouldn't be allowed to spam the log by triggering error
messages; please make this debug instead. Whilst you're there, adding
logs to the other error returns here might be useful.

It seems like everywhere afbc_win is used, it's not actually used for
the window value, but rather just used as an is_afbc_enabled bool. In
that case, it would be better as a real bool, and living in either the
output or plane state.

This would eliminate the need to unset the variable as well.

Relatedly, can one VOP support multiple simultaneous windows using
AFBC? If not, the check that only one window is using AFBC is missing
from this patch.

Unreachable can be WARN_ONCE() rather than a silent return.

Other than that, this is looking a _lot_ nicer than v1 though!

Cheers,
Daniel
