Patch Review

Good refactoring. The switch from `DmaObject` to `KVVec` eliminates unsafe =
pointer manipulation in `patch_signature` and the transmute helpers in fwse=
c.rs.

The new `patch_signature` is safer with proper bounds checking:
```rust
let signature_end =3D signature_start
    .checked_add(signature_bytes.len())
    .ok_or(EOVERFLOW)?;
let dst =3D self
    .0
    .get_mut(signature_start..signature_end)
    .ok_or(EINVAL)?;
```

Minor: The `dev` parameter added to `dma_load` and `load` is now passed thr=
ough the call chain. This is fine =E2=80=94 DMA object creation genuinely n=
eeds the device.

No issues.
