The wcd9310 codec driver which is slimbus slave can access codec
registers when slimbus is suspended.
This can cause register read/write failure.
Fix to make sure slimbus is awake before accessing wcd9310 codec's
registers through slimbus.

Allow the pm8921-charger driver to initiate charging on a
registered 3rd party charging driver through the power supply class.
Also enable the maintenance of charging properties such as online
and charge type using the power supply class rather than
directly depending on the 3rd party driver.
When a external charger is registered using power_supply_register
the external_power_changed callback of the charger driver checks
for an external charger named "dc". This removes the dependency
of a 3rd party charger to call directly into the charger driver.
Also, update the isl9519q driver to reflect the changes and
utilize power supply class calls to enable charging
on the isl chip from PM8921 charger driver.
This serves as an example for other 3rd party external
chargers supporting PMIC with high current charging.
Finally, add pr_fmt macro which automatically adds function name
to print statements and remove __func__ from individual print
statements.

The Charger driver requires the Units of Voltage and temperature
in uV and 0.1 DegC according to the framework where all voltages,
currents, chargers, energies, time and temperature are in uV, uA,
uAh, uWh, seconds and tenths of degree Celsius unless otherwise
stated. In accordance with the above expected units, the scaling
functions are modified for all voltage channels and the Batt Therm.
This change fixes the XO Therm temperature scaling routine,

XO Therm and PA therm units are returned as milli-degree and
degree Centigrade respectively.
Accordingly, update the clients of xoadc to handle this change in
