hw/intc/arm_gicv3: Set GICR_CTLR.CES if LPIs are supported
The GICR_CTLR.CES bit is a read-only bit which is set to 1 to indicate
that the GICR_CTLR.EnableLPIs bit can be written to 0 to disable
LPIs (as opposed to allowing LPIs to be enabled but not subsequently
disabled). Our implementation permits this, so advertise it
by setting CES to 1.
