usb: common: Use helper function for_each_node_with_property()

Browse Source 
for_each_node_with_property() can iterate through the device_node
with a given property name, and we don't need to find the device_node
in the while loop. Since of_device_is_available() will return false if
the "controller" is NULL and break the while loop, there is no functional
change with such conversion.
