qcom-charger: smb138x: fix buck damage on v1.1 hardware
Buck damage was observed because the OOB comparator activated
when HSFET was on, causing a direct short from VBUS to ground. Fix this
on V1.1 by increasing the OOB comparator threshold. On 2.0 this is fixed
by ensuring the OOB comparator activates only after HSFET minimum on
time. This in turn guarantees that HSFET and LSFET won't be on at the
same time.
Since the driver needs to detect the version of the smb, make use of the
qpnp-revid module.
