i915: Reject CCS modifiers for pipe C on Geminilake 

Current code advertises (on the modifiers blob property) support for CCS
modifier for pipe C on GLK, only to reject it later when validating the
request before the atomic commit.

This fixes the tests igt@kms_ccs@pipe-c-*, which should skip on GLK for
pipe C (see bug 104096).
