[U-Boot] [U-Boot, v4, 3/4] usb: dwc3: add support for 16 bit UTMI+ interface

[Kever Yang]

Philipp,

     I believe there are some request I think is not reasonable which 
stop me from update new patch sets.

The usb/dwc3 is mess up now, separate in host mode and gadget mode, one 
need init in board init

while another use DM. When I want to add a new feature like use 16bit 
UTMI+  instead of 8bit(which suppose to be very very simple),

I don't think the maintainer have an idea where it should go and how it 
should be, and the driver now

it's far away from upstream kernel.

I have send 4 patch set for this, everything should be clear, but...



Thanks,
- Kever
