2018-01-30riscv: rename sptbr to satpChristoph Hellwig1-0/+4
satp is the name used by the current privileged spec 1.10, use it instead of the old name. The most recent release binutils release (2.29) doesn't know about the satp name yet, so stick to the name from the previous privileged ISA release and comment on the fact.
