To support the Armada 38x, new values for the request-delay and the response-timeout are needed. As the values already implemented in this tool (for Kirkwood and Armada XP) don't seem to work here. To make this more flexible, lets add make those 2 parameters configurable via the cmdline. Here the new parameters:

-q <req-delay>: use specific request-delay -s <resp-timeo>: use specific response-timeout

For the Marvell DB-88F6820 these values are known to work:

One board: -q 2 -s 1

2nd board: -q 5 -s 5

So this seems to be even board specific. But with this patch now those values can be specified and tested via the cmdline.
