Define the Alt board dependent part of the MMCIF device node. Like the Silk 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 work for the Silk board by Vladimir Barinov and Sergei Shtylyov.
