Subject: [PATCH AUTOSEL for 4.14 049/110] i915: Reject CCS modifiers for pipe
 C on Geminilake

From: Gabriel Krisman Bertazi <krisman@...labora.co.uk>

[ Upstream commit 8bc0d7ac934b6f2d0dc8f38a3104d281c9db1e98 ]

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@..._ccs@...e-c-*, which should skip on GLK for
pipe C (see bug 104096).
