x86/hvm: increase struct hvm_vcpu_io's mmio_large_read[]

Since the emulator now supports a few 256-bit memory operations, this
array needs to follow (and the comments should, too).

To limit growth, re-order the mmio_large_write_* fields so that the
two mmio_large_*_bytes fields end up adjacent to each other.
