[PATCH 04/10] arm64: dts: rockchip: Add Edgeble NCM6A WiFi6 Overlay

[Jagan Teki]

Edgeble NCM6A SOM has on-module M.2 1216-compatible WiFi modules.

Currently, AW-XM548NF WiFi6 and Intel 8260D2W WiFi5 modules are supported.

WiFi modules are fixed on SoM, not pluggable M.2 slots, so different SoM's
for each type of WiFi module.
