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.
