msm: lmh_dcvsh: Support new API to notify scheduler
HLOS can place a mitigation frequency via the LMH DCVSh hardware using
the software cap register and this request doesn't trigger a debug
interrupt. Thus, this frequency mitigation change will not result in
scheduler being notified by LMH DCVSh driver.
Introduce a new API in LMH DCVSh driver, that can be used by other
drivers to trigger the scheduler notification. This API and the
interrupt handler follows the same code path to poll and notify the
scheduler.
