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.
