Hello Christopher,

I went back and re-read the code and the manual, but I'm not sure if PMUSERENR
should be NO_MIGRATE or not. It's only been read/written with this register,
but it also controls EL0 access (i.e., used in pmreg_access). Should we still
add the NO_MIGRATE type to it?
Thanks,
Chengyu
