Subject: [PATCH] add reset props to usb otg/ehci ports
usb resets are needed in case u-boot does its own reset
of the devices, otherwise ports are left in a
non-functional state. Also fixes occasional missing
device detection on the OTG port.
In any case, when reset are present, the iddig filter
wait time always times out, so we comment it as it
looks unnecessary (the port works fine, the device is
always detected also in case of timeout)
