1270b047fd RISC-V: Add satp as an alias for sptbr
The RISC-V privileged ISA changed the name of sptbr (Supervisor Page
Table Base Register) to satp (Supervisor Address Translation and
Protection) to reflect the fact it could be used for more than just
paging.  This patch adds an alias, as they're the same register.
