ACPI: CPPC: Add emtpy stubs of functions for CONFIG_ACPI_CPPC_LIB unset
For convenience, add empty stubs of library functions defined in cppc_acpi.c for the CONFIG_ACPI_CPPC_LIB unset case. Because one of them needs to return CPUFREQ_ETERNAL, include linux/cpufreq.h into the CPPC library header file and drop the direct inclusion of it from cppc_acpi.c. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Tested-by: Chen Yu <yu.c.chen@intel.com>
