Fabio Baltieri 01be4aff40 input: gpio_qdec: add power management support
Add power management support to the gpio-qdec driver.

This is a bit complicated by the fact that the driver has two modes of
operation and the interrupt, timer and idle work ineract with each
other.

The suspend sequence is:
- set the suspended bit (inhibits the poll timer so that it does not
  resubmit the idle work)
- cancel the idle work (so that it does not schedule and re-set the
  interrupt or timers)
- disable interrupts (if used)
- stop the sampling timer
- disconnect the pins

The resume sequence is more or less the opposite.

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-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
