Message

This series improves crc-core <-> driver interface.
This series adds following functionality in the crc-core
 - Now control node will print all the available sources if
   implemented by driver along with current source.
 - Setting of sorce will fail if provided source is not supported
 - cleanup of crtc_crc_open function first allocate memory before
   enabling CRC generation
 - Don't block open() call instead wait in crc read call.

Changes:
 - Rebase on top of VKMS driver
 - Include pre_crc_read patch
