Determine the default CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC from devicetree
when using the Arm SysTick hardware timer.
When the NXP KE1xF SoC series is using the Arm SysTick as hardware
timer, the cycles/second will always be equal to the CPU core clock
frequency.

Add pinctrl-0 properties for configuration of UART, I2C, SPI, FTM,
DAC, ADC, ACMP, and PWT peripherals. These settings are based on what
is defined in the board/pinmux.c file.

Use a combination of fixed-clock and fixed-factor-clock devicetree
nodes for describing the clock dividers/multipliers of the NXP Kinetis
System Clock Generator (SCG) present in the KE1xF SoC series.

Add dts files for the specific chip instances that are used on the
boards in prep of having pin data in devicetree. The pin data will
be specific to the given chip instance so we need to distinguish
unique chips for the same SoC as the pin mux will differ.

In the flash partition definitions for ARM boards,
the link to the legacy partition macros does not
exist any more. The commit cleans up the partition
definition by removing this link.

Do not assume in the SoC level device trees that NXP Kinetis FlexTimer
nodes will always be configured as PWM. Instead, configure FlexTimer
nodes for PWM at the board level for NXP Kinetis boards.

Convert CAN to use a chosen node property that is similar to how we
handle zephyr,entroy or zephyr,flash-controller as the means to select a
specific peripheral instance utilized by a subsystem.
Replace references of the form:
alias {
can-primary = &can1;
};
with:
chosen {
zephyr,can-primary = &can1;
};
Replace various macro/define references with either
DT_CHOSEN(zephyr_can_primary) or replace DT_ALIAS_CAN_PRIMARY_LABEL
with DT_CHOSEN_ZEPHYR_CAN_PRIMARY_LABEL.

Convert driver to use DT_INST_ defines. As part of this conversion we
remove the Kconfig options for per GPIO controller enables and instead
get that information from device tree. This means we now disable each
GPIO controller by default in the DTS and have each board dts enable the
GPIO controller ports it needs.

Have nodelabels match the SoC docs so when a nodelabel reference is
made in the code its easier to relate to the SoC.

Converts the fxos8700 sensor driver to the new gpio api. Updates device
trees for all boards with this sensor to active low gpio interrupts by
default.
Tested on frdm_k64f and rv32m1_vega_ri5cy boards. The latter verifies
that the reset output works correctly.

Update driver code and board files to use new GPIO configuration flags
such as GPIO_ACTIVE_LOW. Also add implementation of new port_* driver
API as well as gpio_pin_interrupt_configure function.
Tested on frdm_k64f board.

This commit introduces the can-primary alias to identify
the primary CAN interface.
This alias is used for all samples and tests, so they don't
need to probe the right interface.

The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.
The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.
The replacement was done with
git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/'
