Jani Nikula b4435717f5 drm/i915: split out vlv sideband registers from i915_reg.h
Add a dedicated file vlv_sideband_reg.h for the VLV/CHV sideband
registers. The sideband registers macros are needed by the same files
that need vlv_sideband.h, so include the definitions from there.

v2: Fix copyright year (Matt)
