Some use cases require higher input currents which are out of range
of USB specification.
Fix this by adding a call to disable the input current limit and
warn the user with an adequate message that input current limiting
is disabled when the function is called

Until now only the BMS system was using the ccadc so there was
no need to create a separate ccadc driver.
However we can run in a configuration with BMS disabled
and clients won't be able to read battery current via ccadc.
Separate the ccadc from the bms, this change in is preparation
to add a ccadc api to read the battery current.

The pmic 8921 charger has a limit of 2Amp of charge current. This limit
makes it inadequate to charge multi-cell batteries.
The pm8921 charger supports a configuration where an external charger
with more current capacity may be used to charge the battery while the
pm8921 itself can charge from a USB source. In such a configuration
the external charger source is connected to the DCIN pins, this makes the
pmic detect insertion and removal of the external charger source. In turn
this enables automatic switching on or off the usb charging path when an
external charger is plugged out or in respectively. The pm8921 charger
driver has to call start and stop on external charger. The internal
FSM and logic correctly indicates that it is charging from a DC source.
The resume charging of a fully charged battery when an external source
is present needs to start charging from an external source. The driver
relies on VBATDET comparator to signal a low.

driver indicates that the battery is fully charged. This value needs
to be calculated when charging ends with a fully charged battery.

The reset interrupt in the pmic indicates the pmic will shutdown
the msm in few seconds - it does so by lowering the reset_n line
to the msm.
When this interrupt is triggered it is required that no more ssbi
transactions are initiated and the msm should cleanup and prepare
for the impending shutdown. There is no need to lower ps_hold in
this case as the pmic will shutdown the msm regardless.
Also since we don't want any ssbi transactions, force shutdown
nonboot cpus. This will prevent ssbi transactions to the pmic for
lower/raising nonboot cpu's voltages as they enter/exit idle states.
