[PATCH v3 2/4] mx6cuboxi: customize board_boot_order to access eMMC

[sbabic at denx.de]

> In SPL legacy code only one MMC device is created, based on BOOT_CFG
> register, which can be either SD or eMMC. In this context
> board_boot_order return always MMC1 when configure to boot from
> SD/eMMC. After switching to DM both SD and eMMC devices are created
> based on the information available on DT, but as board_boot_order
> only returns MMC1 is not possible to boot from eMMC.
> This patch customizes board_boot_order taking into account BOOT_CFG
> register to point to correct MMC1 / MMC2 device. Additionally, handle
> IO mux for the desired boot device.
