From: David Brownell <dbrownell@xxxxxxxxxxxxxxxxxxxxx>
For OMAP3430 SDP, link regulators to the appropriate MMC host adapters.
Note that when MMC1 is used in 8 bit mode (e.g. for an MMCplus card
or CE-ATA device), DAT4..DAT7 I/O uses a separate supply (VSIM).
But MMC_BUS_WIDTH_8 support isn't merged into the MMC framework.
