Subject: [PATCH v2 3/4] usb: musb: omap: use the new API to get PHY reference by label

After the devices are created using PLATFORM_DEVID_AUTO,
devm_usb_get_phy_dev and usb_get_phy_dev can't be used reliably
as it relies on the device_names passed in usb_bind_phy. So used the
new API devm_usb_get_phy_by_name to get the PHY reference.
