usb: dwc3: init phy utmi width in platform data 

On rk3399 board, we need to configure phy interface UTMI+ width
to 16 bits via the property "snps,phyif-utmi-bits" of dwc3 node.
But we can't the get the property from kernel dtb. So this patch
initialize the phy interface UTMI+ width in dwc3 platform data,
and not dependent on the property in dtb.
