hwmon: qpnp-adc-current: Fix specifying batfet status



For the condition when PM8941 is true use the BATFET status
that is passed to the calibration api. Ignore the BATFET
status for all other PMIC versions.

For PM8941 when BATFET is open, the reads on channel 0 for
Internal RSENSE are redirected in HW to channel 0x5:
 EXTRSNS_OFFSET. Recalibrate based on this channel.
