Change Summary:
Update Base addr to set direction to use Aligned IP base address instead
of Port Base Address. Port Base Address + offset to direction register
will set incorrect value for Port B,C & D. For ex: In cases when more than
1 port is configured on the same IP, the DTS node for port B will start
at offset 0xC. Calculating the port using Port Base will yield offset of
PORTB DIR register which is at offset 0x10 from Aligned Base, and as a
result will result in setting DIR register of PORTC instead.

In npcx ec series, two detection levels, 3.3V (default) and 1.8V are
supported during gpio configuration. But the current implementation
always selects default detection level whether NPCX_GPIO_VOLTAGE_1P8 is
set. This PR is a fix for this issue.

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.

Zephyr implementation is limited to 4 IRQ per GPIO bank when up to 8 is
theoritically possible.
It is now possible to use until 8 IRQ per GPIO bank. This can be
achieved with minimal effort in a device tree overlay:
&gpio0 {
interrupts = <4 2>,<5 2>,<6 2>,<7 2>,<32 2>,<33 2>;
};
&gpio1 {
