In some stm32 series systick was disabled in order to
allow alternate use of lptim timer as kernel low power ticker.
Doing this, dts based definition of CORTEX_M_SYSTICK Kconfig symbol
is disabled and CORTEX_M_SYSTICK was redefined with 'default y'
in stm32 soc files which makes things more complex to handle to
alternate with LPTIM activation.

Use kinetis SIM clock divider options set in device tree
instead of hardcoded values.
The kl25z device tree did not previously define a MCG node.
This has now been added with the general "nxp,kinetis-mcg"
binding.

Add some helper macros that will be convenient to use from device
drivers for accessing and error checking pin mux information in the
devicetree:
- NRF_DT_PSEL(): get a PSEL value out of the DT from either a
'foo-pin' or a 'foo-gpios' style property.
- NRF_DT_PSEL_CHECK_NOT_BOTH(), NRF_DT_PSEL_CHECK_EXACTLY_ONE():
helpers for checking that a given devicetree is OK according to
different criteria for setting PSEL properties (NAND or XOR on
whether the properties exist, respectively).
See comments in the patch for more details.

In NPCX7 series, it contains two tachometer (TACH) modules that contains
two Independent timers (counter 1 and 2). They are used to capture a
counter value when an event is detected via the external pads (TA or
TB).
The CL also includes:
— Add npcx tachometer device tree declarations.
— Zephyr sensor api implementation for tachometer.
— Enable "tach1" device in npcx7m6fb.dts for testing.

Since the uart device clock will be stopped after ec entered sleep or
deep sleep state and restore its clock automatically, there is no need
to implement code for suspending and resuming devices manually.
The driver still needs to check the current status of uart device when
it wants to change its power state to LOW or SUSPEND power state. It is
crucial to forbid ec enters sleep or deep sleep state when uart device
is busy with transmitting data. Or we will observe broken characters on
the uart console.

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

This CL introduces a kernel device driver implemented by the internal
64/32-bit timers in Nuvoton NPCX series. Via these two kinds of timer,
the driver provides an standard "system clock driver" interface.
It includes:
- A system timer based on an ITIM64 (Internal 64-bit timer) instance,
clocked by APB2 which freq is CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC.
- Its prescaler is set to 1 and provide the kernel cycles reading
without handling overflow mechanism.
- A event timer based on an ITIM32 (Internal 32-bit timer) instance,
clocked by LCLK which frequency is 32KHz and still activated when ec
entered "idle/deep idle" power state for better power consumption.
- Its prescaler is set to 1 and provide timeout event mechansim.
- Compensate system timer which clock is gating for better power
consumption after ec left"idle/deep idle" power state.
This CL passed starve, timer_api, and timer_monotonic test suites.

In this CL, npcx_miwu_interrupt_configure is no longer responsible for
turning the interrupt off. Although the default state of WK_EN is
disabled, the users still have the chance to configure them when WK_EN
is enabled via npcx_miwu_irq_enable(). Hence, this CL also ensures that
WK_EN is disabled before configuring them.
