usb: dwc3: Add phy interface for dwc3_uboot
U-Boot has two different variants of dwc3 initializations,
- with dm variant gadget, so the respective dm driver would
call the dwc3_init in core.
- with non-dm variant gadget, so the usage board file would
call dwc3_uboot_init in core.
The driver probe would handle all respective gadget properties
including phy interface via phy_type property and then trigger
dwc3_init for dm-variant gadgets.
So, to support the phy interface for non-dm variant gadgets,
the better option is dwc3_uboot_init since there is no
dedicated controller for non-dm variant gadgets.
This patch support for adding phy interface like 8/16-bit UTMI+
code for dwc3_uboot.
This change used Linux phy.h enum list, to make proper code
compatibility.
