Verisilicon display controllers have the hardware cursor feature.

The hardware cursor layer is a simplistic and restrictive layer as the
topmost layer of the display output. It can only support ARGB8888 images
and some certain square power-of-two sizes (32x32 is supported on all
DCs).

This patchset adds support for the hardware cursor as a cursor plane.
