Problem:
The hifi and mailbox driver is different from kernel5.4.
Audiobridge relies on the interfaces of these two drivers.
Solution:
1.Adapt the dsp and mailbox drivers relied on in audiobridge.
2.Solve the problem of out-of-bounds data when mailbox read data from hifi.

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
