cpuidle: Move polling state initialization code to separate file
Move the polling state initialization code to a separate file built conditionally on CONFIG_ARCH_HAS_CPU_RELAX to get rid of the #ifdef in driver.c. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Tested-by: Sudeep Holla <sudeep.holla@arm.com> Acked-by: Daniel Lezcano <daniel.lezcano@linaro.org>
