Similar to the idle, thermal and throttling libraries, always compile
the perflib if CONFIG_ACPI_PROCESSOR is enabled. This not only makes
perflib alligned with other libraries but also helps in some sanity
testing of these ACPI methods even when a particular feature is not
enabled in the kernel configuration.
