Boards may extend or re-define the boot list in their board_boot_order() function by modifying spl_boot_list. E.g. a board might boot SPL from a slow SPI NOR flash and then load the U-Boot from an eMMC or SD-card. Or it might use additional MMC boot device in spl_boot_list for cases when the image in SPI NOR flash is not found, so it could fall back to eMMC, SD-card or another boot device.
Getting the MMC boot mode in spl_mmc will fail when we are trying to boot from an MMC device in the spl_boot_list and the original board boot mode (as returned by spl_boot_device()) is not an MMC boot mode. Fix it by checking the asked MMC boot device from the spl_boot_mode() argument.
