AM64 EVM board has a micro USB 2.0 AB connector and the USB0_VBUS is
connected with a resistor divider in between. USB0_DRVVBUS pin is muxed
between USB0_DRVVBUS and GPIO1_79 signals.
Add the corresponding properties and set the pinmux mode for USB subsystem
in the evm dts file.

Would prefer simple data transfer tests in the log but other than that
for the patches itself

I see:
/workdir/arch/arm64/boot/dts/ti/k3-am642-evm.dt.yaml: cdns-usb@f900000: compatible: 'oneOf' conditional failed, one must be fixed:
I assume there is a reason for this? Can you capture that in the commit
message?
