[PATCH] drm: fix sparse warnings on undeclared symbols in crc debugfs

[Jani Nikula <jani.nikula@xxxxxxxxx>]

Fixes sparse warnings:

drivers/gpu/drm/drm_debugfs_crc.c:118:30: warning: symbol
'drm_crtc_crc_control_fops' was not declared. Should it be static?

drivers/gpu/drm/drm_debugfs_crc.c:264:30: warning: symbol
'drm_crtc_crc_data_fops' was not declared. Should it be static?

drivers/gpu/drm/drm_debugfs_crc.c:281:5: warning: symbol
'drm_debugfs_crtc_crc_add' was not declared. Should it be static?

Fixes: 9edbf1fa600a ("drm: Add API for capturing frame CRCs")
