Subject: [PATCH v2 12/15] arm64: dts: mediatek: mt7981b: Disable wifi by
 default

Disable the wifi block by default as it won't function properly without
at least pin muxing.

This doesn't enable wifi on any of the existing mt7981b devices as a
required memory-region property is missing, causing the driver to fail
probing anyway.
