[PATCH] acpi: Fix warning: 'us_to_pm_timer_ticks' defined but not used

[Kevin Winchester]

Using:

	gcc (GCC) 4.5.0 20100610 (prerelease)

The following warning is seen:

	drivers/acpi/processor_idle.c:83:12: warning: âus_to_pm_timer_ticksâ defined but not used

This is because us_to_pm_timer_ticks is only used when
CONFIG_ACPI_PROCFS is defined.

Fix the warning by moving the function definition into the #ifdef
CONFIG_ACPI_PROCFS block.
