ARM: shmobile: silk: add eMMC DT support
Define the SILK board dependent part of the MMCIF device node (the board has
eMMC chip) along with the necessary voltage regulator (note that the Vcc/Vccq
regulator is dummy -- it's required by the MMCIF driver but doesn't actually
exist on the board).
Based on the original patch by Vladimir Barinov
<vladimir.barinov@cogentembedded.com>.
