There are numbers of drivers for different PCA(L) series chip. They
share similiar register layout and control logic. This driver intends
to unify these drivers for PCA(L)xxxx series i2c gpio expanders.

Use some new kernel features to make the experience of finding and
dealing with GPIO devices much more ergonomic by allowing the use of
devicetree node labels to identify GPIO devices by default.
Users who wish to avoid the associated footprint penalty can set
CONFIG_DEVICE_DT_METADATA=n by hand, but I think the convenience is
worth the price as a default. If we're running a shell, then we've
already paid a heavy footprint penalty.

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.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

RT1718S is an i2c-based TCPC chip that supports 3 additional GPIOs.
The pins can be used for USB-C operations e.g. handling FRS, but they
can also work as usual GPIOs.
Add a driver for the RT1718S GPIO and a handler for an alert signal from
the chip. The handler reads the alert register once asserted and calls
the GPIO interrupt handler if needed(Vendor-defined alert).
gpio_rt1718s.c file and "richtek,rt1718s" node collect common properties
and data for all RS1718S functionalities. The file can be extended for
TCPC driver. rt1718s.h file also defines inline functions with i2c
operations common for all drivers. The common header and source files
can be moved to tcpc directories once the tcpc driver is added since it
is the main functionality.
