gpu: nova-core: Replace module_pci_driver! with explicit module init

Replace the module_pci_driver! macro with an explicit module
initialization using the standard module! macro and InPlaceModule
trait implementation. No functional change intended, with the
exception that the driver now prints a message when loaded.

This change is necessary so that we can create a top-level "nova_core"
debugfs entry when the driver is loaded.
