Add a driver for the charger in the TWL6030/32. For now it does not report
much in sysfs but parameters are set up for USB, charging is enabled with

charging.
This prevents ending up in a system setup where you run out of battery
although a charger is plugged in after precharge completed.

Battery voltage behavior was checked via the GPADC.

Detection (APSD) BC1.2 implementation, as well as Automatic Input
Current Limiting (AICL) to configure the maximum input current
limit of DCP (wall) chargers.

Quick Charge is not currently supported.

Most devices using the smb2 charger have a secondary dedicated charger
chip which is used in parallel to enable faster charger without
overheating. However, not all do, as a result to ensure safety until
these are supported, the maximum current is limited to ~1A via the
FAST_CHARGE_CURRENT_CFG register.
