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

Based on the original patch by Vladimir Barinov
<vladimir.barinov@cogentembedded.com>.

Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

This patch is against 'renesas-devel-20151015-v4.3-rc5' tag of Simon Horman's

Changes in version 2:
- removed non-working SDHI0 stuff, renamed the patch;
- replaced SDHI1's "wp-gpios" property with "disable-wp".
