Xiaoguang Wu ecedf31bd1 DM USB: xHCI: delay 2s for enumeration in resuming process ...

During UOS S3 resume, the UOS will handle USB disconnect flow then
re-enumeration flow due to vbus drop be emulted for UOS S3 case. The
re-enumeration flow will impact UOS S3 resume latency, this patch
delayed the re-enumeration 2s as the workaround for this issue. Need to
do performance optimization in future.

This 2s can be tune which is depend on how fast UOS S3 resume, it should
be as short as possible to make virtual USB device ready immediately
after UOS screen turn on.
