[PATCH 2/2] usb: gadget: dwc2: Set endpoint capabilities via .caps field

[Mattijs Korpershoek]

Endpoint capabilities can be described via the .caps field of
struct usb_ep since commit
77dcbdf3c1ce ("usb: gadget: Add match_ep() op to usb_gadget_ops")

In linux, the following commit introduces it:
b86f33a3a371 ("usb: gadget: epautoconf: add endpoint capabilities flags 
verification")

Linux's change also reworks the ep matching function by relying on
these new capabilities instead of guessing based on the endpoint name.

Prepare the dwc2 UDC driver for capability-based matching by adding the
required capabilities for each endpoint.
