Looks like we need to configure the regulators and use the pdata quirk to make eMMC work with device tree. It seems that mostly vaux3 is used, and only some earlier revisions used vmmc2. This has been tested to work on devices where the system_rev passed by the bootloader has versions 0x0010, 0x2101 and 0x2204.
