docs: pmu: Update the pmu doc with removal of mcountinhbit restriction

Since commit b28f070, it is possible for platforms to run perf monitoring even if mcountinhibit is not supported. Sampling still won't be possible though as it requires sscofpmf extension. Update the docs to remove the restriction. Signed-off-by: Atish Patra <[email protected]> Reviewed-by: Anup Patel <[email protected]>
