linux: Add dts wifi patch for orangepi-zero

Browse source 
The patch with the same name from meta-sunxi is
not applying anymore so we remove from SRC_URI
and add an updated version in meta-balena-allwiner.

Subject: [PATCH] Rework 0001-add-wifi-support.patch
This patch is a rework of the meta-sunxi patch with the same function because
the meta-sunxi patch fails to apply due to different source context in
this kernel version.
Upstream-Status: Inappropriate [backporting]
