Add support for Qualcomm PMIC Battery Current Limiting (BCL) hardware
monitor driver. The BCL peripheral is present in Qualcomm PMICs and
provides real-time monitoring battery overcurrent and under voltage
conditions.

FROMLIST: hwmon: Add Qualcomm PMIC BCL hardware monitor driver
37c3507 
Add support for Qualcomm PMIC Battery Current Limiting (BCL) hardware
monitor driver. The BCL peripheral is present in Qualcomm PMICs and
provides real-time monitoring and protection against battery
overcurrent and under voltage conditions.

The driver monitors:
- Battery voltage with configurable low voltage thresholds
- Battery current with configurable high current thresholds
- Two limit alarm interrupts (max/min, critical)

The driver integrates with the Linux hwmon subsystem and provides
standard hwmon attributes for monitoring battery conditions.
