Leading/trailing whitespace in prompts requires ugly workarounds in
genrest.py, as e.g. *prompt * is invalid RST. strip() all prompts in
Kconfiglib and get rid of the genrest.py workarounds. Add a warning too.
The Kconfiglib update has some unrelated cleanups and fixes (that won't
affect Zephyr).

and configure LSM6DSL on ArgonKey board.
The two named choices introduced in LSM6DSL are:
- LSM6DSL_BUS_TYPE (default LSM6DSL_I2C)

This patch adds dts support to lps22hb/hts221/vl53l0x
I2C sensors as well as lsm6dsl SPI sensor.
Since some info, like gpio for irq triggering or SPI bus
characteristics, may be provided through dts, they need
to be made optional in the LSM6DSL driver by usage of
macros like HAS_DTS_SPI_PINS or HAS_DTS_SPI_DEVICE.

The various macros to do checks in system call handlers all
implictly would generate a kernel oops if a check failed.
This is undesirable for a few reasons:
* System call handlers that acquire resources in the handler
have no good recourse for cleanup if a check fails.
* In some cases we may want to propagate a return value back
to the caller instead of just killing the calling thread,
even though the base API doesn't do these checks.
These macros now all return a value, if nonzero is returned
the check failed. K_OOPS() now wraps these calls to generate
a kernel oops.
At the moment, the policy for all APIs has not changed. They
still all oops upon a failed check/
The macros now use the Z_ notation for private APIs.

The mcux sim clock control driver was originally designed to pass
through the clock subsystem value from dts to the mcux CLOCK_GetFreq()
function. This assumed that the values in
include/dt-bindings/clock/kinetis_sim.h matched the enumeration in
fsl_clock.h, which is true for the coresys, platform, and bus clocks.
However, the low-power oscillator (LPO) clock has a different values in
k64 vs. kw2xd, therefore we must update the clock_control driver to
parse the value from dts and convert it to the fsl_clock.h enumeration.

TimerHandle->Init.Period is used to initialize TIMx ARR register. The
timer will count from 0 up to ARR including, thus it will tick
(ARR + 1) timers per period. As the "period_cycles" variable holds the
number of desired ticks, the ARR register is computed as
ARR = period_cycles - 1
Update the code to reflect this relationship. Otherwise the timer will
count one more tick for each period, leading to a wrong PWM frequency.

Fix a somewhat rare race condition when the thread gets

If the other thread also sends another byte through UART
and "consumes" the EVENTS_TXDRDY value, the first thread
will get stuck in the while loop forever.
By moving the reset to the function start, we guarantee that
the baseline state of EVENTS_TXRDY is 1. Therefore, the first
