Atish Patra 3780e33732 target/riscv: Support mcycle/minstret write operation
mcycle/minstret are actually WARL registers and can be written with any
given value. With SBI PMU extension, it will be used to store a initial
value provided from supervisor OS. The Qemu also need prohibit the counter
increment if mcountinhibit is set.

Support mcycle/minstret through generic counter infrastructure.
