[U-Boot] [PATCH 1/2] poplar: add DWC2 OTG gadget support

[Shawn Guo]

It enables DWC2 OTG gadget driver support for Poplar board.  As
usb2_phy_init() is being always called from board_init(), we can save
the call from board_usb_init().

Yes, but I'll pick them up once the merge window opens again.
