Subject: usb: musb: dsps: kill OTG timer on suspend

From: Felipe Balbi <balbi@xxxxxx>

commit 468bcc2a2ca071f652009d2d20d97f2437630cae upstream.

if we don't make sure to kill the timer, it could
expire after we have already gated our clocks.

That will trigger a Data Abort exception because
we would try to access register while clock is gated.

Fix that bug.
