Out sysreg definitions are largely (but not entirely) in ascending order of op0:op1:CRn:CRm:op2.
It would be preferable to enforce this sort, as this makes it easier to verify the set of encodings against documentation, and provides an obvious location for each addition in future, minimising conflicts. This patch enforces this order, by moving the few items that break it. There should be no functional change.
