drm/i915: Try to print INSTDONE bits for all slice/subslice

Browse source

v2: (Imre)
- Access only subslices that are known to exist.
- Reset explicitly the MCR selector to slice/sub-slice ID 0 after the
  readout.
- Use the subslice INSTDONE bits for the hangcheck/subunits-stuck
  detection too.
- Take the uncore lock for the MCR-select/subslice-readout sequence.
