[4/5] usb: dwc2: gadget: Replace phyif with phy_utmi_width

[Jules Maselbas]

The phy utmi width information is already set in hsotg params,
phyif is only used in few places and I don't see any reason to
not use hsotg's params.

Moreover the utmi width was being forced to 16 bits by platform
initialization which doesn't take in account HW configuration.
