This looks really nice. I'm currently working on a series of patches to
add shared mailboxes to the HSP driver. Part of that series adds struct
device *dev to struct tegra_hsp, which in turn would simplify this
patch a little.

Looking at some of the changes here it also seems like they would
conflict with my patches in some places. Would you mind if I pick this
patch up into my series and resolve the conflicts there?
