The ADC architecture on PMIC7 is changed as compared to PMIC5. The
major change from PMIC5 is that all SW communication to ADC goes through
PMK8350, which communicates with other PMICs through PBS when the ADC
on PMK8350 works in master mode. The SID register is used to identify the
PMICs with

Add documentation for PMIC7 ADC peripheral.
For the PMIC7-type PMICs, ADC peripheral is present in HW for the
following PMICs: PMK8350, PM8350, PM8350b, PMR735a and PMR735b.
Of these, only the ADC peripheral on PMK8350 is exposed directly to SW.

So add support for loading the m3 firmware before q6.
Now the drivers works fine for both split and unified
