[PATCH RESEND] 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.
