[PATCH v2 09/10] gpu: nova-core: remove `io::` qualifier to register macro invocations

[Alexandre Courbot <acourbot@nvidia.com>]

The kernel's `register` macro would clash with nova-core's own version
if it was imported directly, so it was accessed through its `io` module
during the conversion phase.

Now that nova-core's `register` macro doesn't exist anymore, we can
import and use it directly without risk of name collision.
