ARM: shmobile: Lager and Koelsch USB prototype patches

[PATCH 01/05] gpio: rcar: Per-controller gpios property prototype
[PATCH 02/05] ARM: shmobile: Lager DT reference USB platform devices
[PATCH 03/05] ARM: shmobile: Lager DT reference USB pinmux setup 
[PATCH 04/05] ARM: shmobile: Koelsch DT reference USB platform devices
[PATCH 05/05] ARM: shmobile: Koelsch DT reference USB pinmux setup

These patches enable USB functionality for the DT reference
board support for Lager and Koelsch. With these in place it is
possible to use a single kernel binary with CCF and MULTIPLATFORM
on Lager or Koelsch and use USB Host or USB Function even though
DT bindings are not yet developed for such device drivers.

This is intended as a short term prototype to show that USB
can be used on R-Car Gen2 hardware such as Lager and Koelsch
even though DT bindings are not yet in place.

Based on the legacy Lager and Koelsch board code written by Valentine
and Vladimir, but slightly reworked to include clock workarounds and
DT-style GPIO handling. The first patch in this series is a prototype
to allow board code written in C to access GPIOs on controllers
described via DT.

Not for upstream merge.

 The Koelsch code has a run time dependency on:

For reference I would prefer if the above patches were prefixed with

ARM: shmobile: lager: 

> [PATCH 04/05] ARM: shmobile: Koelsch DT reference USB platform devices
> [PATCH 05/05] ARM: shmobile: Koelsch DT reference USB pinmux setup

And likewise if the above patches were prefixed with

ARM: shmobile: koelsch:
