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.

To reset USB DRD role is one workaround for adb lost issue with xDCI
passthrough which reproduced in S3 stress test.
This workaround will involve the system global reset if xDCI working in
SuperSpeed mode. This is maybe caused by PMC firmware can't graceful
power gate the xDCI during S3 suspend. The current USB DRD driver will
set STATIC switch bits which will cause ungraceful DRD switch, it may
make the xDCI enter a unknown state, then involved this global reset
issue.
BTW, base on latest code base, the adb lost issue can't reproduce even
remove this workaround. So remove the old workaround for above reasons.

To support discard for virtio-blk, the backend file should also located
in a filesystem which support discard. So, mount /data partition with '
-o discard'.
Then, add 'discard' to virtio-blk to enable this feature.
1. Erase operations on UOS will trigger the discard on SOS instead of
writing zero, which will save erase time.
2. Discard in storage firmware will move the mapped host address range to
the unmapped host address range. So, when delete a file in UOS, discard
will trigger the space collection on storage, so that in the next write
operation, it need not to do erase first.

Support DISCARD command is meaningful when eMMC usage is high or
there are lots of remove operations. For example, when Guest
Android is running, there will be lots of files being created and
removed. However, virtio-blk BE does not support DISCARD command,
data remove operation in UOS will not trigger erase in eMMC. After
period of time, the eMMC will be consumed out, and erase must be
done by eMMC firmware before writing any new data. This causes the
eMMC performance decrease in the whole system (SOS and UOS).
To solve the problem, DISCARD should be supported in virtio-blk BE.
