Subject: [PATCH v2] arm64: dts: allwinner: h6: PineH64 model B: Add wifi

PineH64 model B contains RTL8723CS wifi+bt combo module.

Since bluetooth support is not yet squared away, only wifi is enabled
for now.

Acked-by: Chen-Yu Tsai <wens@...e.org>
Signed-off-by: Jernej Skrabec <jernej.skrabec@...l.net>
