gpu: nova-core: Blackwell: use absolute FBHUB0 flush registers

Browse source

The GB20x sysmem flush registers were defined relative to an Fbhub0Base
register window, but there is exactly one FBHUB0 base, so expressing them
as base-plus-offset only adds indirection.

Rename these to FBHUB0 and give them their fixed absolute addresses,
dropping the base struct and its RegisterBase impl.

No functional changes.
