riscv: Improve PTDUMP to show RSW with non-zero value
RSW field can be used to encode 2 bits of software
defined information. Currently, PTDUMP only prints
"RSW" when its value is 1 or 3.

To fix this issue and improve the debugging experience
with PTDUMP, we redefine _PAGE_SPECIAL to its original
value and use _PAGE_SOFT as the RSW mask, allow it to
print the RSW with any non-zero value.

This patch also removes the val from the struct prot_bits
as it is no longer needed.
