ACPI: Make ACPI processor proc I/F depend on the ACPI_PROCFS
Now whether the ACPI processor proc I/F is registered depends on the CONFIG_PROC. It had better depend on the CONFIG_ACPI_PROCFS. When the CONFIG_ACPI_PROCFS is unset in kernel configuration, the ACPI processor proc I/F won't be registered.
