There is a dependency for the CCADC calibration work on the BMS
driver. This prevents some devices that do not use the BMS
to utilize the CCADC.
Remove this dependency by moving the ccadc calibration
work to the CCADC driver to avoid this.

pm8921 chip is equipped with a smart battery gauge called bms.
BMS is capable of intelligently measuring battery parameters
under various loads, the software uses these reading to
accurately determine battery capacity.
Add driver for the bms module.

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 smb137b chip from SUMMIT is a Switch Mode charger chip capable
of charging through USB source. It can also provide VBUS when the
system is a host. The driver exposes the charger properties via
the power_supply class. It also interacts with the usb driver for
insertion/removal notifications and charge current information.
The driver also turns off charging and switches to providing VBUS
when told to do so by USB driver.
