regulator: pf9453: Improve documentation for pf9453_regulator_set_ramp_delay_regmap

The function pf9453_regulator_set_ramp_delay_regmap lacked detailed
parameter descriptions and return value explanations in its documentation.
This patch improves the documentation by adding specific details about
the parameters, their usage, and the return values, enhancing clarity for
developers.
