PATCH 1/1 acpi: fix unused function warning

Len, Is this known issue?

=========================================================
When CONFIG_ACPI_PROCFS=n, processor_idle.c makes following warning.

drivers/acpi/processor_idle.c:83: warning: 'us_to_pm_timer_ticks' defined but not used.

This patch fixes it.
