Please reindex this, downstream uses _1 for pmic@0, but this
makes little sense. Make it match the SID.

What happened to the downstream _2 (pmic@2) one and _4 (pmic@6)?

Please use the naming from the schematics for these things, rather than
just an iterator (which might be what Bartosz is doing here).

Not sure how to approach that. All currently existing
"qcom,spmi-temp-alarm" nodes use the PMIC name for the label.
Otherwise it would have to go into the board file and be replicated
for each board using the same PMIC?
