This is touching ACPICA header file, so it must be submitted to ACPICA
separately following the guidelines in the github and imported into the
kernel.

However, I don't see any point in this change. Yes the language "doorbell"
is not used in this particular context in the spec, but it is implicit from
other parts. I am not opposing the change though if Rafael is OK and ACPICA
project accepts it.
