Fix segfault accessing menvcfg when U-mode doesn't exist
The simplest fix is to create the CSRs even if they don't need to exist,
and just skip adding them to the CSR map to prevent the target machine
from being able to access them.
It looks like there are other place we should be following this pattern:
e.g. why does sstatus exist if S-mode does not exist? But that's a
matter for another day.

Fix ePMP checking on hlvx instructions
The hlvx instruction must grant PMP permissions of both execution and
reading. Thus, with ePMP (mseccfg.MML==1), the hlvx instructions are
only permitted with pmpcfg.RWXL=0111 from M-mode.
