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.

Support new PMIC PF9453, which is totally difference with PCA9450. So
create new file for it.
The PF9453 is a single chip Power Management IC (PMIC) specifically
designed for i.MX 91 processor. It provides power supply solutions for IoT
(Internet of Things), smart appliance, and portable applications where size
and efficiency are critical. The device provides four high efficiency
step-down regulators, three LDOs, one 400 mA load switch and 32.768 kHz
crystal oscillator driver.
