Marked the irq-gpios property as "required: true" in the yaml file.
This ensures that the property is always defined in the device tree,
preventing the driver from crashing when irq-gpios is missing.

The it8801 template is helpful but in the current state it does not
allow changing the device address as that is in the template itself. Fix
that by moving the template content down a level in the hierarchy, so
that it extends the mfd device itself rather than than instantiate it,
then the base instance can have any address, now the only limitation is
that only one instance is possible, but that is probably alright for
now.
Alternatives would be to use a define for the address, or even a
template per address, but this feels like a better compromise for now.
This may also use
https://github.com/zephyrproject-rtos/zephyr/pull/82825 in the future if
that ever becomes a thing.

Add mfd_adp5585 and gpio_adp5585 driver. This driver enables ADP5585
as an GPIO expander.
This chip is used as an GPIO expander on i.MX93 EVK. GPIO pinctrl,
read/write and interrupt is supported.
Note that ADP5585 has 2 GPIO banks with 5 pins each. The driver combines
two group into a 16-bit port. Index 0~4 correspond to R0~R4 lines, index
8~12 correspond to C0~C4 lines. Index 5~7 is reserved unavailable.

By default N_VBUSEN signal is used by the host to define if VBUS
signal should be used for power supply (VBUS-IPSOUT).
This feature enables the possbibility to change this behaviour.
When N_VBUSEN detection is disabled, axp192 will automatically
decide to use VBUS (REG10H[7] = 1).
Please refer to datasheet for details.

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.
