ACPI: processor: idle: Fix function defined but not used warning 

If CONFIG_ACPI_PROCESSOR_IDLE=n, acpi_processor_register_idle_driver()
and acpi_processor_unregister_idle_driver() are never used and the
empty stubs of them are not needed.  Moreover, they cause the compiler
to complain [1], so remove them.
