gpu: nova-core: convert hshub0 from relative register to projection

This commit converts the hshub0 relative access to use projection and a new
base, similar to previous conversions.

[Severity: Low]
This isn't a bug, but should these imports be alphabetically sorted? 

The kernel vertical import style usually requires sorting items alphabetically,
so Io and Mmio would typically precede the lowercase entries.

[Severity: Low]
This isn't a bug, but is the #[inline] annotation needed here? 

The Rust subsystem guidelines suggest reserving #[inline] for abstractions,
and specifically note that leaf crates like drivers are exempt from needing it.
