[PATCH v7 18/24] usb: gadget: at91_udc: set endpoint capabilities

[Anders Roxell <anders.roxell@linaro.org>]

The resynced epautoconf.c matches endpoints on the caps field, not on the
name. at91_udc never fills caps in, so usb_ep_autoconfig() finds no
endpoint after the resync. Same problem dwc2 had, fixed in commit
c5c4cc4c6b98 ("usb: gadget: dwc2: Set endpoint capabilities via .caps
field").

Move the endpoint names into a table together with their capabilities,
the way the kernel driver does it, and copy the caps into the endpoint.

Compile tested only.
