ACPI: OSL: Use spin locks without disabling interrupts
After commit 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler for SCI") any ACPICA code never runs in a hardirq handler, so it need not dissable interrupts on the local CPU when acquiring a spin lock. Make it use spin locks without disabling interrupts. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
