Device Tree "num-ports" property of USB host node has to be set to maximum number of ports available. The possibility to activate a particular port is done by specifying the proper gpio configuration for its vbus. This patch fixes the USB host node by configuring the 3 ports available on the product and letting "port A" available for USB gadget usage.
