arm_gicv3_kvm: kvm_dist_get/put: skip the registers banked by GICR
While we skip the GIC_INTERNAL irqs, we don't change the register offset accordingly. This will overlap the GICR registers value and leave the last GIC_INTERNAL irq's registers out of update. Fix this by skipping the registers banked by GICR. Also for migration compatibility if the migration source (old version qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then we shift the data of PPI to get the right data for SPI.
