Andy Ross fc392a2c75 tests/kernel/tickless/tickless_concept: Force 100 Hz ticks
This test was written to assume ~100 Hz ticks in ways that are
difficult to fix.  It wants to sleep for periods on the order of the
TICKLESS_IDLE_THRESH kconfig, which is extremely small on high tick
rate systems and (on nRF in particular) does not have a cleanly
divisible representation in milliseconds.

Fixing precision issues by cranking the idle threshold up on a
per-system basis seems like an abuse, as that is what we want to be
testing in the first place.  Just let the test run at the tick rate it
has always expected.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
