Move common USB charger code out of board directory including
setting VBUS supplier when VBUS changes, and initializing BC1.2
supplier types on init.
This also enables re-enabling of Pericom BC1.2 detection interrupts
when VBUS is changed on all boards that use USB_CHG task.

TEST=make -j buildall. Tested on glados and samus by plugging in
a few different chargers and making sure we charge.

Previously we supported using a single pi3usb9281 chip, or using two
chips on the same i2c bus behind a mux. Now that we need to support a
third configuration of multiple chips on different busses, it makes
sense to be able to configure the configuration freely at the board
level.

Previously, the 5V rail was disabled unconditionally in the S0->S3
transition. Now, the rail is left powered if one or both of the USB
ports are powered.

the EC console, 'gpioget pp5000_en' should be 1.

"Auto" mode is observed to cause problems and thus is removed. This
leaves only three modes:
- Standard downstream port. USB 2.0 mode. 500mA.
- Charging downstream port. BC1.2. 1500mA.
- Dedicated charging port. BC1.2. 1500mA.

Implement TPS2543 USB charging control.
It contains routine for setting each USB port as dedicated charging port
or standard downstream port. To allow us controlling the current
