Convert the enable, pwm, and retention `gpios` properties away from the
GPIO specifier space to an integer array.
While this is a less specific type than the GPIO property, it has the
advantage of not requiring the PMIC gpios node to be both present and
enabled.

There is a HW bug in nPM1300 LDO which causes the LDO output voltage to
reach its target very slowly in specific cases. This is worked around by
performing an additional i2c read shortly after an LDO is enabled.

Some Nordic SoCs, like nRF52 contain an internal regulator for the main
SoC supply. Depending on the SoC, the regulator can have multiple
configurations (e.g. single/double stage), which mainly depends on
supporting "high-voltage" mode or not (VDDH pin supply). This patch adds
bindings for nRF5X regulator and nRF52X HV regulator.

Possible situation is that in some driver, devices can be controlled in
different ways: in some, we can only turn the power on or off, in others,
we can only control the voltage, and in some, we can control power supply
or voltage level. There may also be devices where there is no control
over power supply at all. A clear example of this can be eMMC devices
where the voltage is usually fixed and they are always powered on.
However, we would like to have a common code for controlling all the
mentioned types of devices, at least the driver shouldn't worry about the
implementation details of voltage regulators. Therefore, there may exist
empty regulators - regulators that only contain information about the
supported voltage, and we cannot change anything in them. The device tree
node description for such a regulator is only necessary for compatibility
with other regulators. Hence, we need to add the possibility of the
existence of such a dummy fixed-regulator.
In this commit, support for a fixed dummy regulator without the ability
for any control has been added. Note that such support also exists in the
Linux kernel. In other words, the logic of the fixed regulator has been
aligned with the logic of the fixed regulator inside the Linux kernel.

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.

While nPM1100 is to be operated in fixed configuration for some
applications, it has some degree of configuration via GPIOs. For
example, mode (auto/PWM) can be configured via MODE pin. VBUS current
can also be adjusted using ISET pin, even though there is no API yet to
limit the PMIC input current.
This patch adds a new regulator class driver for nPM1100 PMIC, so that
it can be used with the standard regulator API when needed.
