slim: msm: Support deferred response during system suspend
If runtime-pm does not get a chance to enter low-power mode before
system suspend is called, system suspend may need 2 passes since
power-off request needs to be sent to audio-DSP using QMI, and QMI
acquires wakelock if response is expected right-away.
Use Deferred-response during suspend to avoid 2 passes, and inquire
the power-off status when system resumes in that case.
