Define the SILK board dependent part of the SDHI1 (connected to micro-SD slot)
device nodes along with the necessary voltage regulators.

This patch is against 'renesas-devel-20150810-v4.2-rc6' tag of Simon Horman's
'renesas.git' repo plus the R8A7794/SILK QSPI patches just re-posted. It needs
the R8A7794 GPIO patches in order to compile.
Changes in version 2:
- removed not working SDHI0 stuff, renamed the patch;
- replaced SDHI1's "wp-gpios" property with "disable-wp".

Oops, need a newline here. I'll repost.
