target/riscv: actual functions to realize crs 128-bit insns
The csrs are accessed through function pointers: we add 128-bit read
operations in the table for three csrs (writes fallback to the
64-bit version as the upper 64-bit information is handled elsewhere):
- misa, as mxl is needed for proper operation,
- mstatus and sstatus, to return sd
In addition, we also add read and write accesses to the machine and
supervisor scratch registers.
