drm/ast: cursor: Calculate checksum in helper
Setting the cursor image requires a 32-bit checksum of the cursor
image data. The current cursor code converts the image to ARGB4444
format and computes the checksum in a single step. Moving the
checksum calculation into a separate helper will allow to move the
format conversion into a shared helper.
v2:
- don't loop for checksum'ing final pixel (Jocelyn)
- fix typo in commit message (Jocelyn)
