From: Chris Morgan <[e-mail]>

Add support for the Texas Instruments BQ25703 charger manager. The
device integrates a boost converter with the charger manager. This
series adds the device as an MFD with separate regulator and power
supply drivers. This allows us to manage a circular dependency with
a type-c port manager which depends on the regulator for usb-otg
but supplies power to the bq25703 charger.

Requesting comments on this series as I want to confirm this is the
best way to integrate these functions.
