[PATCH 0/2] gpu: nova-core: falcon: use I/O projections for DMA transfers

Falcon DMA transfers were using cumbersome handle arithmetic and
explicit bounds checks to ensure a requested transfer is valid. This
series replaces this with an I/O projection which, if successful,
carries the same bounds guarantees and does not require performing
operations on DMA handles.

The first patch removes a redundant check that is covered by the
register's `try_with_...` family of methods.

This patchset is based on top of drm-rust-next.
