netif_carrier_off would be called when autoresuming, even though
the cable is plugged. This causes some applications do relative
actions when detecting the carrier off. Keep the status of the
carrier, and let it be modified when the linking change occurs.

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.

This patch prepares the introduction of the generic PHY support in the
USB OTG common functions. The USB PHY member of the OTG structure is
renamed to 'usb_phy' and modifications are done in all drivers accessing
it. Renaming this pointer will allow to keep the compatibility for USB
PHY drivers.

This patch modify the generic code handling PHYs to allow them to be

there when looking for one in the generic code. This also makes sure we

This patch adds support of the PHY framework for ChipIdea drivers.
