[kvm-unit-tests PATCH 1/3] lib/riscv: Also provide sbiret impl functions

[Andrew Jones]

We almost always return sbiret from sbi wrapper functions so
do that for sbi_get_imp_version() and sbi_get_imp_id(), but
asserting no error and returning the value is also useful,
so continue to provide those functions too, just with a slightly
different name.
