The Nuvoton NCT38xx is a multi-function device providing a TCPC
controller and a I/O expander (GPIO driver). Add a multi-function
driver to manage exclusive access to the device.
Tested with "twister -T tests/drivers/build_all/gpio".

AXP192 is a small and simple power management IC featuring different
LDOs, DCDCs, AINs and also GPIOs. It also offers functionaltiy for
battery management.
This change includes the basic regulator driver functionaltiy for
LDO2-3 and DCDC1-3 as well as the mfd driver layer. Further drivers
for GPIO and ADC will follow.
Drivers have been developed and tested on M5StackCore2, an ESP32-based
board. Support for M5StackCore2 is still in progress.

Added an MFD driver for the nPM1300.
This driver has register access helper functions that can be used
by subsystems. This will avoid each subsystem having to duplicate
the register access code.

Add an API-less MFD driver for nPM6001. In this case, the MFD device
driver doesn't expose any API as plain I2C API is used within other
device drivers (regulator, GPIO, watchdog). This driver just initializes
some device properties.

Introduce the skeleton for multi-function device drivers. This driver
class is inspired by the same class found in Linux. Multi-function
devices expose multiple functionalities, for example, a LED driver,
regulator, GPIO controller, etc. The MFD driver class serves as a kind
of "parent" device where common functionality can be managed: bus
access, IRQ sharing, initialization code, etc.
