dt-bindings: pinctrl: aspeed: Add g4 USB functions
The AST2400 contains several USB controllers:
* USB 1.1 Host Controller
* USB 2.0 Host Controller
* USB 2.0 Virtual Hub
* USB 1.1 HID Controller
Pins for three ports are routed to the three controllers such that:
* Port 1 is a dedicated USB 1.1 host port
* Port 2 is shared between the USB 1.1 host and HID controllers
* Port 3 is shared between the USB 2.0 host and Hub controllers
As the pins for port 1 are fixed function there is no associated mux
function or group described in the bindings. Ports 2 and 3 are muxed as
above, and the table below describes the mapping between pinmux function
names and ports:
Port | USB Version | USB Mode | Mux Function
------|--------------|-----------|-------------
1 | 1.1 | Host | -
2 | 1.1 | Host | USB11H2
2 | 1.1 | HID | USB11D1
3 | 2.0 | Host | USB2H1
3 | 2.0 | Device | USB2D1
