This patch has a build-time dependency on "sh_eth: add support for gpio reset".
This patch has a run-time dependency on "sh_eth: add support for r8a7790 SoC".

v4
* Annotate ether_platdata as __initdata

v3
* Rebase

v2
* As suggested by Laurent Pinchart
  - Do not manipilate sh_eth reset GPIO directly,
    rather, do so through newly proposed support for this in
    the sh_eth driver.
* A suggested by Sergei Shtylyov
  - Move DTS portion into a separate patch
