Subject: [REPOST PATCH 2/4] usb: dwc2: Turn on uframe_sched on "his" platforms

There's no reason to have the uframe scheduler off on dwc2.  Running
with uframe_sched = False is equivalent to saying "I don't want to run
the correct code, I want to run the old and incorrect code".

The uframe scheduler has been off on HiSilicon since commit
37dd9d65cc41 ("usb: dwc2: add support of hi6220").  Since then there
have been many many improvements, notably the commit 9f9f09b048f5
("usb: dwc2: host: Totally redo the microframe scheduler")

Presumably if everyone is good w/ the uframe_sched turned back on we
can kill all the old and crufty non-uframe sched code.
