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()
