RISC-V: Raise access fault exceptions on PMP violations
Section 3.6 in RISC-V v1.10 privilege specification states that PMP violations
report "access exceptions." The current PMP implementation has
a bug which wrongly reports "page exceptions" on PMP violations.

This patch fixes this bug by reporting the correct PMP access exceptions
trap values.
