Add an asmlinkage wrapper around acpi_enter_sleep_state() to prevent an empty stub from being called by assmebly code for ACPI_REDUCED_HARDWARE set. As arch/x86/kernel/acpi/wakeup_xx.S is only compiled when CONFIG_ACPI=y and there are no users of ACPI_HARDWARE_REDUCED, currently this is in fact not a real issue, but a cleanup to reduce source code differences between Linux and ACPICA upstream.
