[PATCH v3] arm64: dts: rockchip: Add rfkill for wireless modules for Radxa ROCK 5A

[FUKAUMI Naoki]

Radxa ROCK 5A has a M.2 E key slot which can be used for wireless
modules. There are two enable/disable switch pins, one for Wi-Fi,
another for Bluetooth. These pins are connected to GPIO.

Add rfkill and rfkill-bt to control these pins via GPIO.
