The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().
