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.

Deprecate dcsr.halt
The debug spec 1.0.0-rc3 deprecates the dcsr.halt and lets the bit
become dcsr.nmip.
This commit separates the halt variable from the dcsr.nmip and
designates it as an internal variable for halt_on_reset (-H).
Additionally, this commit removes the notifying comment about the
deprecated dcsr.halt in the main loop.
