Bin Meng f77549fe74 riscv: sifive: Fix OF_BOARD boot failure
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().

Fixes: 2e8d2f8843 ("riscv: Remove OF_PRIOR_STAGE from RISC-V boards")
Fixes: d6f8ab30a2 ("treewide: Remove OF_PRIOR_STAGE")
