ACPI / sleep: Introduce CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT
ACPI 5.1 does not currently support S states for ARM64 hardware but ACPI code will call acpi_target_system_state() and acpi_sleep_init() for device power management, so introduce CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT and select it for x86 and ia64 only to make sleep functions available, and also introduce stub function to allow other drivers to function until S states are defined for ARM64. It will be no functional change for x86 and IA64. Suggested-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Acked-by: Rafael J.
