[Bjorn Andersson <bjorn.andersson@linaro.org>]

There are no other pending changes colliding with this, so if Andy is okay with
this it could be merged through Kalle's tree - together with the other patches.

Marcel, with this applied we can drop the depends on QCOM_SMD from the
btqcomsmd driver as well.

Changes since v3:
- Added this patch to allow compile testing without SMD support after patch 2
