H A Drockchip_drm_vop.c582212ee Mon Oct 31 12:16:01 CDT 2022 Brian Norris <briannorris@chromium.org> drm/rockchip: vop: Quiet always-warning AFBC log

The downstream code from which this was derived didn't ever run through
this 'switch' block with non-AFBC formats, but the upstream code does --
we use this function to probe whether a given format is supported.

Demote the warning to eliminate this sort of warning seen on every
boot:

[drm] unsupported AFBC format[3231564e]

And make it warn more than once, because if we *actually* care to see
what formats we're probing/rejecting and for what reasons, we probably
care about more than just the first message.

Drop the comment, because one of the two *is* commonly reachable.

And lastly, drop the unreachable return; we'd do better to let the
compiler complain if we start hitting this unexpectedly.
