The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

In usb_hub_configure the hub is asked for its descriptor and among other things
its bPwrOn2PwrGood time. In the actual hub_power_on function this information
was not used and a hardcoded value was used instead. For some hubs this delay
is to short. So, use the delay the hub wants.

ehci: speed up initialization
According to EHCI specification v1.0, the controller should stabilize
the power on a port at most 20 ms after the port power bit transition.
So, we put this setting in the virtual descriptor corresponding field,
(bPwrOn2PwrGood = 10 => 10 x 2ms = 20ms), this saves about 500ms at each
controller initialization/enumeration.

This patch makes the USB command optional and makes usb_rescan a
global function. This way we can use USB in noninteractive
environments.
