Add PMBus hwmon driver and DT binding for the Analog Devices MAX20860A
step-down DC-DC switching regulator. The driver provides monitoring of
input/output voltage, output current, and temperature using linear data
format.

The driver does not modify device write-protection state during probe and
relies on the PMBus core to handle write-protect detection and sysfs
attribute permissions.

Tested on PTX platform with MAX20860A at i2c-195/0x23:
  - All sensors (vin, vout, iout, temp1, temp2) read correctly
  - Limit attributes correctly read-only (HW write-protect honored)
  - Clean dmesg (no probe errors)

Changes since v2:
  - DT binding: Drop "maxim,max20860a" and keep only "adi,max20860a"
  - Driver: Drop matching "maxim,max20860a" OF match entry

Changes since v1:
  - DT binding: Added allOf regulator.yaml reference and unevaluatedProperties
  - Driver: Removed WRITE_PROTECT write from probe
