usb: hub: Fix enumration timeout
Patch b6d7852c increases timeout for enumeration, taking worst case to be 10 sec. get_timer() api returns timestamp in milliseconds, which is what we are checking in the do-while() loop in usb_hub_configure() (get_timer(start) < CONFIG_SYS_HZ * 10). This should give us a required check for 10 seconds, and thereby we don't need to add additional mdelay of 100 microseconds in each cycle.
