drm/arm/malidp: Implemented the size validation for AFBC framebuffers
AFBC buffers include additional metadata which increases the required
allocation size. Implement the appropriate size validation and sanity
checking for AFBC buffers.
Added malidp specific function for framebuffer creation. This checks
if the framebuffer has AFBC modifiers and if so, it verifies the
necessary constraints on the size, alignment, offsets and pitch.
Changes from v2:
- Replaced DRM_ERROR() with DRM_DEBUG_KMS() in
malidp_verify_afbc_framebuffer_caps() and malidp_verify_afbc_framebuffer_size()
