power: qpnp-charger: Avoid override USBIN_COMP in reverse boost for SMBBP 



When SMBBP working at reverse boost mode with a charger connected, USBIN
comparator can be used to turn off the OVP FET and trigger an USBIN_VALID
IRQ to detect the charger removal.

Avoid overriding USBIN comparator when SMBBP working at reverse boost
mode, to ensure the charger insertion and removal can be detected.
