power: qpnp-charger: add parallel ovp charge mode

This enables the parallel OVP charge mode for PM8941 devices.
This feature specific to PM8941 allows DC_IN and USB_IN to be
shorted on the device to allowing both input paths to be leveraged
and put more current into the battery.

Note that the feature is only enabled when fast charging
and disabled once fast charging is disabled.
