pda_power: Add optional OTG transceiver and voltage regulator support

This patch allows machines to use an OTG transceiver driver instead of
supplying a custom is_usb_online callback to check USB power.
Also, in the case that the OTG transceiver handles charger control when
connected to USB, a regulator named "ac_draw" can be supplied instead of
the custom set_charge callback to control the charger when connected to
AC.

The check for (transceiver->state == OTG_STATE_B_PERIPHERAL) in
otg_is_usb_online is probably too simple, I'm just using this with a
peripheral only device and gpio_vbus + bq24022. I'm not sure which other
OTG states can supply power.
