defconfig: Enable generic USB audio driver
i2c: chips: fsa9480: Add support for charging in USB-OTG mode

If an OTG-cable with a power-adapter is connected, the phone will be
able to charge.
As the power-source might be damaged if it's not capable to provide
the current needed for charging, this feature is disabled by default
and can be enabled by writing "slow" or "fast" to
/sys/class/sec/switch/otg_charger_type

The allowed values are:
none -> no charging in USB-OTG mode (default)
slow -> usb charging in USB-OTG mode
fast -> wall charging in USB-OTG mode
