sdm660-common: Change USB autosuspend delay to 7s by commandline.
b/71936484 has audio accessories failing to connect
when there's a transition to suspend when they're attempting
to enumerate.
Avoid this problem by increasing autosuspend delay
from the default 2s to 7s.
The longest I've seen a device take to enumerate after
vbus is ~3 seconds, this gives a 2x margin.
Test: booted on Walleye, saw no more messages:
[ 472.412555] c0 5675 msm-dwc3 a800000.ssusb: DWC3 in low power mode
between device connection and enumeration.
Bug: 71936484
