We want to store the GSP and SEC2 falcon instances inside the `Gpu`
structure, but doing so require these types to implement `Send` for
`pci::Driver` to remain implementable on `NovaCore`, which embeds `Gpu`.

All implementors of `FalconEngine` and `FalconHal` satisfy the
requirements of `Send`, and these traits also already required `Sync`,
so this a minor tweak.
