arm64: dts: allwinner: h616: orangepi-zero2w: add 24-pin expansion overlay
This adds a devicetree overlay for the optional 24-pin expansion board, which
provides two buttons on LRADC channel 0 and an IR receiver.

[Severity: Medium]
Are the USB 2.0 nodes missing here?
The base board device tree (sun50i-h618-orangepi-zero2w.dts) explicitly leaves
USB 2 and 3 disabled, expecting them to be enabled by an overlay. Without
references to &ehci2, &ehci3, &ohci2, and &ohci3, the physical USB ports on the
24-pin expansion board will remain disabled and non-functional when this
overlay is applied.
Could these nodes be added so the expansion board is fully supported?
