    drivers/usbhost_hub: Add support to Multiple TT HS HUB
    
    This is the case for USB2517 USB HUB. Also improved the driver to
    avoid mistakes: initially I changed g_id[3], but the in register
    there is another field where we need to pass this size again. So
    it is better to use ARRAY_SIZE() macro to avoid mistakes.
