[GIT PULL] simple-mfd cleanup

Hi ARM SoC maintainers,

as discussed back and forth with Lee Jones & Arnd, here is the patch
set adding the "simple-mfd" subtree analogous to "simple-bus". I have
not got the attentions of some subsystem maintainers but I'm out of
patience and thus assume they just don't care. However for us in the ARM
OF/DT camp this is of great value.

It is mainly a cleanup, but since the Juno + ARM64 LED support depend
on it that has been added on top, tell me if you prefer that in a separate
pull request and I'll send you two individual ones instead.

Cleanups from Antoine Tenart and Alexandre Belloni depend on this.

Please pull this in.
