Rotation memory for layers is shared with AFBC decoder block. Thus one need=
s to
calculate rotation memory requirement in case of AFBC framebuffer. This is
used later to verify if it can be sufficed by the hardware rotation memory
availibility.

Fixes: 66da13a ("drm/arm/malidp: Validate rotations for compressed/uncompre=
ssed framebuffers for each layer")
