From: Sagar Kamble <sagar.a.kamble@intel.com>

With this patch we allow larger cursor planes of sizes 128x128
and 256x256.

v2: Added more precise check on size while setting cursor plane.

v3: Changes related to restructuring cursor size restrictions
and DRM_DEBUG usage.

v4: Indentation related changes for setting cursor control and
implementing DRM_CAP_CURSOR_WIDTH and DRM_CAP_CURSOR_HEIGHT

Testcase: igt/kms_cursor_crc
