usb: gadget: config: remove max speed check in usb_assign_descriptors()

JIRA: https://issues.redhat.com/browse/RHEL-122021

commit 4dfdd90
Author: Linyu Yuan <quic_linyyuan@quicinc.com>
Date: Thu, 3 Aug 2023 17:10:51 +0800

  usb_assign_descriptors() usally called inside function bind operation,
  and gadget still have no working connection speed, let's support all
  speed at this point, it may possible allocate extra memory to store
  descriptors, but it is small and acceptable.

  Remove gadget_is_{*}speed() API checking to allow support all speed.
