drm/i915: Enabling 128x128 and 256x256 ARGB Cursor Support
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
