[PATCH v5 1/9] usb: move the OTG state from the USB PHY to the OTG structure

From: Antoine Tenart
Date: Mon Sep 15 2014 - 06:43:10 EST

Before using the PHY framework instead of the USB PHY one, we need to
move the OTG state into another place, since it won't be available when
USB PHY isn't used. This patch moves the OTG state into the OTG
structure, and makes all the needed modifications in the drivers
using the OTG state.
