Subject: [PATCH v8 5/7] usb: chipidea: rename transceiver and phy to usb_phy
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.
