[0/4] drm/i915: add dedicated lock for each sideband

Message

It's misleading to use the same sideband mutex for LPT/WPT IOSF, VLV/CHV
IOSF, and punit. Add dedicated locks for clarity.

Jani Nikula (4):
  drm/i915/sbi: add intel_sbi_{lock,unlock}()
  drm/i915/sbi: add a dedicated mutex for LPT/WPT IOSF sideband
  drm/i915: add a dedicated mutex for VLV/CHV IOSF sideband
  drm/i915: hide VLV PUNIT IOSF sideband qos handling better
