Daniel Golle ac7f5641e9 drm/mediatek: Only touch DISP_REG_OVL_PITCH_MSB if AFBC is supported ...

[ Upstream commit f8d9b91739e1fb436447c437a346a36deb676a36 ]

Touching DISP_REG_OVL_PITCH_MSB leads to video overlay on MT2701, MT7623N
and probably other older SoCs being broken.

Move setting up AFBC layer configuration into a separate function only
being called on hardware which actually supports AFBC which restores the
behavior as it was before commit c410fa9b07 ("drm/mediatek: Add AFBC
support to Mediatek DRM driver") on non-AFBC hardware.
