svn commit: r323641 - head/sys/arm/allwinner (BananapiM3 [an A83T] and USB: BPI-M3 historically had usb nodes listed in ofwdump -a)

[I went looking in the tree for head -r323676
and found *.dts* files listing usb things for
the BPI-M3 and a83t. So I add notes about that.]

I might not have found all the usb references
but the below is a start.

/usr/src/sys/boot/fdt/dts/arm/sinovoip-bpi-m3.dts has:

&ehci0 {
        status = "okay";
};

&ehci1 {
        status = "okay";
};
. . .
&reg_usb1_vbus {
        gpio = <&pio 3 24 GPIO_ACTIVE_HIGH>;    /* PD24 */
        status = "okay";
};

&usb1_vbus_pin_a {
        allwinner,pins = "PD24";
};

&usbphy {
        usb1_vbus-supply = <&reg_usb1_vbus>;
        status = "okay";
};

Via #include there is:

/usr/src/sys/boot/fdt/dts/arm/sun8i-a83t.dtsi has:

                bus_gates: clk at 01c20060 {
                        . . .
                        clock-output-names = . . .
                                             "bus_spi1", "bus_usb_otg",
                                             "bus_ehci0", "bus_ehci1",
                                             "bus_ohci0", "bus_ve",
                                             . . .
                };

/usr/src/sys/gnu/dts/arm/sunxi-common-regulators.dtsi has:

&pio {
        . . .

        usb0_vbus_pin_a: usb0_vbus_pin at 0 {
                pins = "PB9";
                function = "gpio_out";
        };
