This patchset adds cursor plane support and compute CRC for output frame
with cursor and primary plane.

changes in v2:
- clear alpha channel before computing crc for XRGB plane format
- add module option 'enable_cursor' to enable/disable cursor support

This patch compute CRC for output frame with cursor and primary plane.
Blend cursor with primary plane and compute CRC on the resulted frame.

This currently passes cursor-size-change, and cursor-64x64-[onscreen,
offscreen, sliding, random, dpms, rapid-movement] from igt
kms_cursor_crc tests.

Cursor support is not complete yet. Add module option 'enable_cursor'
to enable/disable cursor support which is used for testing currently.
