Alexandre Mergnat cd956f5aa6 target/riscv: Fix pmp NA4 implementation 
The end address calculation for NA4 mode is wrong because the address
used isn't shifted.

It doesn't watch 4 bytes but a huge range because the end address
calculation is wrong.

The solution is to use the shifted address calculated for start address
variable.

Modifications are tested on Zephyr OS userspace test suite which works
for other RISC-V boards (E31 and E34 core).
