ACPI: Decouple ACPI idle and ACPI processor drivers
This patch introduces a new Kconfig symbol, ACPI_PROCESSOR_IDLE, which is auto selected by architectures which support the ACPI based C states for CPU Idle management. The processor_idle driver in its present form contains declarations specific to X86 and IA64. Since there are no reasonable defaults for other architectures e.g. ARM64, the driver is selected only for X86 or IA64. This helps in decoupling the ACPI processor_driver from the ACPI processor_idle driver which is useful for the upcoming alternative patchwork for controlling CPU Performance (CPPC) and CPU Idle (LPI).
