gpu: nova-core: add DMA object struct Since we will need to allocate lots of distinct memory chunks to be shared between GPU and CPU, introduce a type dedicated to that. It is a light wrapper around CoherentAllocation.

gpu: nova-core: apply the one "use" item per line policy As per [1], we need one "use" item per line, in order to reduce merge conflicts. Furthermore, we need a trailing ", //" in order to tell rustfmt(1) to leave it alone. This does that for the entire nova-core driver.

gpu: nova-core: Simplify `DmaObject::from_data` in nova-core/dma.rs This patch solves one of the existing mentions of COHA, a task in the Nova task list about improving the `CoherentAllocation` API. It uses the `write` method from `CoherentAllocation`.
