arm64: dt: rockpi4: disable node usbdrd_dwc3_0 #106

Closed jforissier closed 1 year ago

If a USB-A to USB-A cable is used to flash the RockPi4 eMMC as described in [1], it is likely that the board will be booted with the cable still plugged into the board and into the computer on the other side. Such a configuration results in periodic error messages from the kernel:

[ 4.832697] usb usb6-port1: Cannot enable. Maybe the USB cable is bad? [ 4.833416] usb usb6-port1: config error

That is annoying, especially since the messages are also sent to the console by default, which could mess up with CI scripts. Therefore, disable this port (it is the upper USB3 blue port; the lower one will still work fine).

Thanks @jenswi-linaro I have also added **not for mainline** similar to other DT patches that we carry in this Git.
