airoha: an7581: enable USB node on eMMC RFB board

Browse Source 
Enable USB node on eMMC RFB board and disable USB2 3.0 port to make the
3rd PCIe line correctly work.

This is needed to prevent the xHCI driver to mess with PCIe by
configuring the USB2 3.0 port. Port will still be detected but won't be
configureed by the driver and won't have PHY to configure for.
