drm/i915: Add horizontal mirroring support for CHV pipe B planes
The primary and sprite planes on CHV pipe B support horizontal mirroring. Expose it to the world. Sadly the hardware ignores the mirror bit when the rotate bit is set, so we'll have to reject the 180+X case. v2: Drop the BIT() v3: Pass dev_priv instead of dev to IS_CHERRYVIEW() Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1479142440-25283-4-git-send-email-ville.syrjala@linux.intel.com
