Atish Patra a26dc609df lib: sbi: Disable interrupt and inhibit counting in M-mode during init ...

Currently, the mhpmevent CSRs are untouched during hart init during
cold/warm boot. Ideally, we should clear out all the bits except
overflow and MINH bit. That is required to disable overflow
interrupt and inhibit counting in M-mode to avoid any spurious
interrupts before perf start.
