Commit 9ad63986c6 (pda_power: Add support for using otg transceiver events)
converted the pda-power driver to use otg events to determine the status
of the power supply.
As gpio-vbus didn't use otg events until now, this change breaks setups
of pda-power with a gpio-vbus transceiver.
This patch adds the necessary otg events and notifiers to gpio-vbus.
