drm: crc: Introduce verify_crc_source callback

This patch adds a new callback function "verify_crc_source" which will
be used during setting the crc source in control node. This will help
in avoiding setting of wrong string for source.

Changes since V1:
 - do not yet verify_crc_source during open.
Changes since V1:
 - improve callback description
