Some coprocessor register access functions need to be able
to report "trap to EL3 with an 'uncategorized' syndrome";
add the necessary CPAccessResult enum and handling for it.
I don't currently know of any registers that need to trap
to EL2 with the 'uncategorized' syndrome, but adding the
_EL2 enum as well is trivial and fills in what would
otherwise be an odd gap in the handling.
