gpio_pin_interrupt_configure asserts that one of GPIO_INT_ENABLE or
_DISABLE is specified by the caller, and also that GPIO_INT_EDGE is
requested if both states (GPIO_INT_TRIG_BOTH) should interrupt. This
change corrects the misuses in it8xxx2 drivers that cause assertion
failures.
When assertions are disabled the existing code works correctly because
the it8xxx2 GPIO driver assumes that a pin interrupt should be enabled
if _DISABLE is not requested, and the driver only supports edge
triggers but assumes the absence of GPIO_INT_MODE_LEVEL indicates
an edge trigger was requested.

Handle eSPI periperal channel error to avoid continous interrupt
beyond the bus error.
Whenever an eSPI access causes an internal bus error,
PC_BUS_ERROR bit is set, it remains set until cleared by written

This corrects the following:
1. The priority of type cast is lower than member access. So don't need
the redundant parentheses.
2. The macro should be added to the parentheses.

The KBC/ACPI event data is 4-byte in width and composed of
event/data/type fields. However, the field position is defined by each
chip vendor via macro and not unified in the current implementation.
The commit uses the structure bit field to define and unify the field
position. It helps the application access it with a common approach.

This CL replaces series-prefix "npcx7-" with family-"npcx-" for npcx dts
nodes such as 'espi-vws-map' and 'miwus-int-map'. Since we plan to
introduce the npcx9 and later series, adding a new node such as
npcx9-espi-vws-map for each series is more complicated and not
necessary.

This CL introduces power management driver that improves the efficiency
of ec operation by adjusting the chip’s power consumption to the level
of activity required by the application in npcx series.
The following list summarizes the main properties of the various chip
power states. Please refer the power.c file for more detail.
Main power states in npcx series include:
- Active: Core, RAM and modules operate at the clocks generated by PLL.
- Idle: Enter this state when the Core executes WFI or WFE instruction.
- Sleep: clock is stopped for most of modules but PLL is enabled.
- Deep Sleep: As Sleep mode but PLL is disabled.
- Standby: All power rails are turned off besides standby and battery
power rails.
And this CL implements one power state, PM_STATE_SUSPEND_TO_IDLE, with
two sub-states for Zephyr power management system.
Sub-state 0 - "Deep Sleep" mode with “Instant” wake-up if residency
time is greater or equal to 1 ms
Sub-state 1 - "Deep Sleep" mode with "Standard" wake-up if residency
time is greater or equal to 201 ms

Keep OOB Rx channel and interrupt always enabled.

Note that driver doesn't perform any buffering from packets,
so access to OOB Rx channel is gated by client's driver
packet retrieval.
