Since pistachio/bluetooth driver is not upstreamed, we might want to cleanup pistachio-bt and hostport related patches and squash into logical group. All the fixup related patches can be squashed.

Ci40 doesn't have the frontend needed to support BT directly from the SoC hence we have the CSR chip on-board. So no need for support any of the pistachio BT.
