Add support for reading ADC channels on a PMIC7 ADC directly from
the ADC_PBS peripheral on that PMIC instead of through PMK8350
ADC peripheral using PBS, for targets where PMK8350 does not run in
master mode.
The conversion request sequence for using ADC_PBS is similar to
the existing one for ADC7, with some differences in register
writes. In addition, SW now performs calibration in place of PBS,
for every conversion, by reading the three calibration channels,
calculating the reference values and entering them in the
calibration registers.

Currently, when an ADC7 channel is read, there is a wait time of
10 ms where an EOC (end of conversion) interrupt should happen
thereby completing the wait for ADC conversion. However, if this
wait times out, it is not handled and stale data can be read. Add
error logs to print when this wait times out as well as if EOC
bit is not set and return an error.
Also, this 10 ms wait time for EOC after requesting for a channel
conversion is not sufficient. As per the hardware recommendation
when multiple subsystems requests PMIC HW arbiter to read same
or different channels on different PMICs simultaneously, it could
take 15 ms for a good case i.e. where all the conversion requests
went through successfully. However, for a worst case where this
conversion request times out, it could take up to 500 ms before
an EOC interrupt is sent by PBS to SW. Hence, increase conversion
wait time to 501 ms so that no other channel reads can be made in
the worst case. Also print a warning when the wait time for EOC
is more than 15 ms.
