tests/pm_pc8: add support for runtime PM
We try to detect if we have runtime PM or if we just have PC8. In case
there's runtime PM, the functions that wait will wait for the runtime
PM status reported by the sysfs file instead of waiting for PC8
residencies to move.

run: ./pm_pc8 --run-subtest i2c
