The end address calculation for NA4 mode is wrong because the address used isn't shifted.
That imply all NA4 setup are not applied by the PMP. 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).
