Rk3399 vop big can support one afbc decoder, the afbc decoder
can select which overlay window use it.

on vop hardware, we call afbc decoder as afbdc.

afbdc window has some limit:
   1, not support offset on source buffer.
   2, if feed non-afbc buffer to afbc decoder, afbc decoder hardware
      would die, we need take care of using it.

AFBC is a compressed format, means lower bandwidth consume,
it's useful to improve performance.
