Add a driver for the Qualcomm PMI8998/SDM660 Switch-Mode Battery Charger
"2". This replaces the previous SMBB hardware found in older PMICs.

This driver provides basic support for initialising the hardware,
configuring the USB input current limit and reporting information about
the state of the charger. Features like type-c dual role support and OTG
switching will be added in future patches.

This patch series depends on my previous series adding support for
the Round Robin ADC which is used for reading the USB voltage and
current, it can be found here:
