Please name this "pon", just for consistency.

Can you confirm that pm8009 is subtype 1, and hence the reboot reason
going into RB_SPARE should be shifted 2 steps, rather than 1 as in the
newer PMICs?

Would be nice if we had a generic compatible that read the subtype,
rather than having to add new compatibles for each pmic (or use the old
ones)...
