ACPI: processor: idle: Add module import namespace 



Add a new module import namespace called ACPI_PROCESSOR_IDLE for
functions exported from the non-modular part of the ACPI processor
driver to the modular part of it.

Export acpi_processor_claim_cst_control() and acpi_processor_evaluate_cst()
in that namespace to hide them from unrelated modules.

They are also used by the intel_idle driver, but it is non-modular,
so it can call them regardless of the way the symbols are exported.
