It looks like in order to have a functional system the shmobile patches
need at least some of the pinctl patches. Probably the shmobile
and pinctl patches can be merged in parallel. But regardless I am marking
the shmobile patches as deffered until the pinctrl patches are accepted.

FWIW, I think it ought to be possible to supply slimmer DT files that
allow for a working system without any PFC dependencies. This may allow
some Gose support to be merged faster.
