I don't think we need to hide the struct from the caller. This is all
host1x internal. Even if a host1x client uses the struct it makes little
sense to hide it. They are all part of the same code base so there's not
much to be gained by hiding the structure definition.

We can probably do that. It might make some sense to keep it in order to
scope the related fields but struct host1x isn't very large yet, so I
think omitting host1x_intr should be fine.
