Revert "ACPI: EC: Use a spin lock without disabing interrupts"
Commit eb9299beadbd ("ACPI: EC: Use a spin lock without disabing
interrupts") introduced an unexpected user-visible change in
behavior, which is a significant CPU load increase when the EC
is in use.
This most likely happens due to increased spinlock contention
and so reducing this effect would require a major rework of the
EC driver locking. There is no time for this in the current
cycle, so revert commit eb9299beadbd.
