driver: intc: add MIWU driver support in NPCX series.
The device Multi-Input Wake-Up Unit (MIWU) supports the embedded
controller (EC) to exit 'Sleep' or 'Deep Sleep' power state which allows
chip has better power consumption. Also, it provides signal conditioning
such as 'Level' and 'Edge' trigger type and grouping of external
interrupt sources of NVIC. The NPCX series has three identical MIWU
modules: MIWU0, MIWU1, MIWU2. Together, they support a total of over 140
internal and/or external wake-up sources.
In this CL, we use device tree files to present the relationship bewteen
MIWU and the other devices in different npcx series. For npcx7 series,
it include:
1. npcx7-miwus-int-map.dtsi: it presents relationship between MIWU group
and NVIC interrupt in npcx7. Please notice it isn't 1-to-1 mapping.
2. npcx7-miwus-wui-map.dtsi: it presents relationship between input of
MIWU and its source device such as gpio, timer, eSPI VWs and so on.
This CL also includes:
1. Add MIWU device tree declarations.
2. MIWU api function declarations and implementation to configure signal
conditions and callback function mechanism. They can be be classified
into two types. One is for GPIO which connects original gpio callback
implemetation and the other is for generic devices such as timer,
eSPI, and so on.
