[PATCH v8 21/25] usb: musb-new: set endpoint capabilities

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

musb-new sets maxpacket directly and leaves caps empty, so
usb_gadget_ep_match_desc() rejects every endpoint once epautoconf.c comes
from the kernel.

The shared fifo endpoints need both directions, the others only the one
they are wired for. The kernel driver already gets this right.

Take the caps and the usb_ep_set_maxpacket_limit() calls from the kernel
driver.

Compile tested only.
