The reason I avoided doing this is that this
conflicts with qemu coding style which
only uses camel case for types.
So as a minimum this needs a comment
explaining that we are using the names from
ACPI spec as-is, that's why we deviate from
the coding style, to simplify matching against
that.
Something like below:

We probably should add in spec link as well.

Not sure about these ones.
There's a single user, and naming is different
from rest of operators which makes it
a bit confusing.
Maybe define near the user?

Hmm if we are doing this let's do this for all Ops.
