This follows the same logic as 82d40b141a4c ("arm64: dts: rockchip: add
rfkill node for M.2 Key E WiFi on rock-5b").
On the orangepi-5-plus, there's also a GPIO pin connecting the WiFi
enable signal inside the M.2 Key E slot.
The exact GPIO PIN can be validated in the Armbian rk-5.10-rkr4 kernel
rk3588-orangepi-5-plus.dtsi file [1], which contains a `wifi_disable`
node referencing RK_PC4 on &gpio0.
