From: Bjorn Andersson <quic_bjorande@quicinc.com>

sc8280xp-pmics define the two thermal zones "pm8280-1-thermal" and
"pm8280-2-thermal", but the related temp-alarm instances are not tied to
any adc channels, and as such continuously report the bogus temperature
of 37C.

After previously defining these adc channels across all boards using
sc8280xp-pmics.dtsi, we can now add these references.

This does however mean that we have a non-disabled node referencing
default-disabled nodes, requiring each board to enable the pmk8280_vadc.
Avoid this by marking pmk8280_vadc okay.
