drivers: qcom: rpmh: avoid sending sleep/wake sets immediately
Fix the redundant call being made to send the sleep and wake requests immediately to the controller. As per the patch [1], the sleep and wake request votes are cached in rpmh controller and sent during rpmh_flush(). These requests needs to be sent only during entry of deeper system low power modes or suspend.
