arm64: dts: rockchip: add analog audio to RK3588 EVB1

Add support for the EVB1 analog audio to its devicetree. Only
the headphone has been tested, since I don't have matching
peripherals to test headset or speakers.

I also didn't manage to record sound from the onboard microphone,
but that also fails with the vendor kernel. Thus I assume the
microphone on my board is fried.
