Peng Fan 66668c77cb fix(gicv3): wait rwp when gicr_ctrl.enablelpis from 1 to 0 
Per GIC architecture version 3 and version 4, Where the GICR_CTRL.EnableLPIs
remains programmable:
- Software must observe GICR_CTLR.RWP==0 after clearing GICR_CTLR.EnableLPIs
  from 1 to 0 before writing GICR_PENDBASER or GICR_PROPBASER, otherwise
  behavior is UNPREDICTABLE.
- Software must observe GICR_CTLR.RWP==0 after clearing GICR_CTLR.EnableLPIs
  from 1 to 0 before setting GICR_CTLR.EnableLPIs to 1, otherwise behavior is
  UNPREDICTABLE.

After changing EnableLPIs from 1 to 0, wait RWP got cleared, otherwise
setting EnableLPIs from 0 to 1 may fail.
