Adopt the driver core lifetime infrastructure for nova.
Use the lifetime-bound pci::Bar directly in NovaCore, eliminating the
Arc<Devres<Bar0>> indirection. This lets SysmemFlush borrow the Bar and
implement Drop for automatic cleanup.
Replace ARef<Device> with plain borrows in SysmemFlush and the GSP sequencer,
where the structs are already lifetime-parameterized.
Separate the driver type from the driver data to allow the private data
to be lifetime-parameterized via the Data GAT.
This patch series is based on [1] and drm-rust-next.
