ACPI: OSL: Use spin locks without disabling interrupts
After commit 7a36b901a6
("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.
