Alex Bennée ba3581de79 hw/intc: avoid byte swap fiddling in gicv3 its path 
This allows us to keep the MSI data in plain host order all the way
from the MemoryRegionOps write method to the final KVM_SIGNAL_MSI
ioctl. This fixes a theoretical bug on big-endian hosts because we
were using different size byte swaps which would have truncated the data.
