Possible fix for trap concurent with xret. Fixes the priority so trap has higher priority than either sret or mret. Previous code had priority to xret in the trap logic and privilege logic, but not the csrsr logic. This caused partial execution of the instruction.

made machine timer bit of IP registers unwriteable so it can only change when the interrupt actually changes

I think this version of csri matches what is required in the spec. ExtIntS should not be written into the SEIP register bit.

Switched csri IP_REGW to use assignements rather than always_comb as this is incompatible with forcing.
