From: Ayan Kumar Halder <ayan.hal...@arm.com>

Considering the fact that some of the AFBC specific pixel formats are expressed
in bits per pixel (ie bpp which is not byte aligned), the pitch (ie width * bpp)
is not guaranteed to be aligned to burst size (ie 8 or 16 bytes).
For example, DRM_FORMAT_VUY101010 is 30 bits per pixel. For a framebuffer of
width 32 pixels, the pitch will be 120 bytes which is not aligned to burst size
(ie 16 bytes) for DP650.
