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 c410fa9b07c3 ("drm/mediatek: Add AFBC support to Mediatek DRM driver") on non-AFBC hardware.

DC driver is using two different values to define the maximum number of surfaces: MAX_SURFACES and MAX_SURFACE_NUM. Consolidate MAX_SURFACES as the unique definition for surface updates across DC. It fixes page fault faced by Cosmic users on AMD display versions that support two overlay planes, since the introduction of cursor overlay mode.

Fix by setting out-scale size as zero when the dst size is zero, similar to what is done by drm_calc_scale(). This issue started with the introduction of cursor ovelay mode that uses this function to assess cursor mode changes via dm_crtc_get_cursor_mode() before checking plane state.
