PD#SWPL-139800
Problem:
SC2 far field voice need early suspend and record
with dsp.
Solution:
When DSP waked up by VAD, then:
1. DSP notify to AOCPU (would fail by unknown cmd) and ARM
during early suspend.
2. DSP notify to AOCPU (would fail by unknown cmd) and ARM
(would fail by timeout) and do retry after ARM deep sleep and
before AOCPU STR poweroff.
3. DSP notify to AOCPU after AOCPU STR poweroff.
4. when ffv not supported, dsp do not start vwe.

Problem:
1.kernel5.15 M4 reconstruction
2.bl40/mfh start smc uses different cmd
3.dsp start/suspend/remap smc uses different cmd
but there are dsp functions, so need to use the same cmd together
Solution:
1.kernel5.15 M4 reconstruction
2.bl40 and mfh smc cmd uses the same
3.dsp start/suspend/remap smc cmd uses the same

Problem:
sc2 not have dsp,resources have been released,but also register misc,
so When sc2 autostart,it accesses the /dev/hifi4dsp0 node,
so causing a panic in load firmware
Solution:
when board not have dsp,resources have been released,then return
negative value
Verify:
