[PATCH v2 0/2] arm64: dts: allwinner: H616: Add LRADC

Version 2 moves the LRADC DT node to the right place. It was out of
order before.

The Allwinner H616 series of SoCs have a low-rate ADC (LRADC) with
6-bit resolution and one input channel. They're compatible with the
existing drivers, so it only needs to be enabled in the DT.

Add an LRADC node to the H616 .dtsi, so board DTs can use them by
adding 'status = "okay";'.

This was tested on an OrangePi Zero 2W by attaching an expansion board
with two key buttons connected to the LRADC, and adding them to the DT.
/dev/input/event0 then properly reported the button presses. The patches
are based off sunxi/for-next.
