As the bots have already told you, you missed adding a 'wifi' label to
sdm845.dtsi, so this reference doesn't compile.

That's not a legit node name. Nodes should (a) have a generic name and
(b) include a unit address when the node contains a 'reg' property. [1]

So, how about 'wifi@18800000'? (And include the 'wifi:' label, since you
want to refer to it in other files.)

Also, this seems like the kind of device that should remain 'status =
"disabled"' in the top-level DTSI, and be overridden with 'status =
"okay"' in the child DTS.

I am fine with 'wifi@18800000'.

Sure, i will populate  'status = "disabled"' in next revision, which can 
be enabled from child dtsi
as part of separate change.
