target/riscv: Add cycle & instret privilege mode filtering support

QEMU only calculates dummy cycles and instructions, so there is no
actual means to stop the icount in QEMU. Hence this patch merely adds
the functionality of accessing the cfg registers, and cause no actual
effects on the counting of cycle and instret counters.
