Message-Id: <20230123064021.2657670-1-Naresh.Solanki@9elements.com>

Subject: [PATCH 1/4] hwmon: (pmbus/core): Generalize pmbus status flag map
The PMBus status flag map(pmbus_regulator_status_flag_map) is moved
outside of the regulator #if block and the associated variable/struct
name updated to reflect as generic PMBus status.
This will make the PMBus status flag map more versatile and easier to
incorporate into different contexts and functions.
