drm/rockchip: Add per-pixel alpha support for the PX30 VOP
Compared to its predecessors, the PX30 VOP has a different register layout
for enabling per-pixel alpha. Instead of src_alpha_ctl and dst_alpha_ctl,
there is a single alpha control register. This register takes some fields
from src_alpha_ctl, but with a different layout.
Add support for the required fields to the PX30 VOP window descriptions,
which makes per-pixel-alpha formats behave correctly.
