Subject: [PATCH] xen/acpi: Fix Kconfig dependency on CPU_FREQ
The functions: "acpi_processor_*" sound like they depend on CONFIG_ACPI_PROCESSOR
but in reality they are exposed when CONFIG_CPU_FREQ=[y|m]. As such
update the Kconfig to have this dependency and fix compile issues:
ERROR: "acpi_processor_unregister_performance" [drivers/xen/xen-acpi-processor.ko] undefined!
ERROR: "acpi_processor_notify_smm" [drivers/xen/xen-acpi-processor.ko] undefined!
ERROR: "acpi_processor_register_performance" [drivers/xen/xen-acpi-processor.ko] undefined!
ERROR: "acpi_processor_preregister_performance" [drivers/xen/xen-acpi-processor.ko] undefined!
Note: We still need the CONFIG_ACPI
