drm/radeon/kms: improve bpc handling (v2)
Improve handling of bpc (bits per color) in radeon. In most cases we want 8 except for HDMI, DP, LVDS, and eDP. v2: handle DP better. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Tested-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
