I've applied both patches into a temporary branch for likely 4.18 now
with the tags from Shawn.

Reason is that we also have a fix for 4.16 in a different branch fixing
the ep-gpios property on sapphire and having these things conflict
will end up in a lot of chaos, as that fix is not yet in the mainline kernel
but only in an intermediate state.

So likely the pcie move will have to wait for 4.18 to make it easier
on everybody.
