hwmon: (pmbus/lm25066) add current limit configuration support

Browse source

Add support for the 'ti,current-range' devicetree property to configure
the current limit via the DEVICE_SETUP (0xD9) register, overriding the
physical CL pin setting.

This configuration is supported on all chips in this driver (LM25066,
LM5064, LM5066, LM5066i) except LM25056.

The property values "low" and "high" map to:
- LM25066: low = 25 mV, high = 46 mV
- LM5064, LM5066, LM5066i: low = 26 mV, high = 50 mV

The Bit 4 mapping to High/Low current limit is handled dynamically on
probe because it is swapped for LM25066 compared to the other supported
chips.
