Ok will do this, I hope there won't be any corner cases where the link is
down when start_xfer happens. I was not really sure about the history, thats
why tried to incorporate my fix into the above IF check.


It was initially implemented verbatim base on the Start Transfer command
suggestion from the programming guide without considering the dwc3
driver flow. First dwc3 checks for U1/U2/U3 state. Then we fixed to only
check for L1/L2/U3 state, but it's still not right. I've had this on my
TODO list for awhile and haven't made an update since it's not critical.

Sure, thanks for the confirmation, will send v2.
