usb: disable L1 LPM
NAK'ed OUT transfers never complete once the usb controller enters
L1 LPM. The issue was rootcaused to the usb controller not performing
remote wakeup when it enters L1 and a trasaction is queued.
Since, this is entirely controlled by controller's hardware,
disable L1 lpm to prevent transfer failure.
Also, init already has the required sepolicy to write to sysfs nodes.
Bug: 124354097
Test: already verify on some laptops and check bcdUSB field
