Changes in v2:
- Remove qcom,enabled-strings property as either it or qcom,num-strings should be present. qcom,num-strings is specified and sufficient. (Marijn Suijten's Suggestion)

Unlike the number of connected strings and configured ovp/current limits, aren't external-pfet (and probably switching-freq, perhaps CABC) hardware features that are common across all users of `pmi8998`?
