[igt-dev] [PATCH i-g-t] tests/kms_available_modes_crc limit tested fb formats

[Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com>]

This test is causing too much useless noise. Limit tested
fb formats to DRM_FORMAT_C8 and DRM_FORMAT_XBGR2101010 for now.
These two formats are currently not tested otherwise thus
they're left here for now. DRM_FORMAT_XBGR2101010 need to be
included into IGT supported formats and DRM_FORMAT_C8 test need
to be moved elsewhere, maybe into kms_plane.
