Subject: [PATCH v7 5/7] usb: rename transceiver and phy to usb_phy in ChipIdea

This patch prepares the introduction of the generic PHY support in the
USB ChipIdea common functions. The USB PHY member of the ChipIdea
structure ('transceiver') is renamed to 'usb_phy', the 'phy' member of
the ChipIdea pdata 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.
