power: qpnp-charger: Add a regulator device to control flash led WAs
Flash led relies on SMBB to supply the 5V drive voltage. Add a regulator
device in qpnp-charger driver to support flash related workarounds in
SMBB.
While at it, add a SMBB temperature threshold workaround in the
regulator device. On certain devices SMBB/SMBBP over temperature
happened at default settings before flash module start thermal derating.
Raise the SMBB over temperature threshold when regulator enabled, and
restore to default setting when regulator disabled.
