[linux-yocto] [yocto-4.12][PATCH 14/36] drm/i915/cnl: Cannonlake has same MOCS table than Skylake.

[Liwei Song]

From: Rodrigo Vivi <rodrigo.vivi at intel.com>

commit 1dc0766c33473d61fd85caa5031daf34f719cd3f upstream.

All registers and default configuration are the same for Skylake
and Cannonlake.

v2: Don't apply Wa for platforms without MOCS. (Paulo)

v3: Removed WaDisableSkipCaching that Joonas noticed that
according to spec it is not applicable to CNL.
