When using QEMU to have a quick test of booting U-Boot S-mode payload directly without the needs of preparing the SPI flash or SD card images for SiFive Unleashed board, as per the instructions [1], it currently does not boot any more. This was caused by the OF_PRIOR_STAGE removal, as gd->fdt_blob no longer points to a valid DTB. OF_BOARD is supposed to replace OF_PRIOR_STAGE, hence we need to add the OF_BOARD logic in board_fdt_blob_setup().
