Availability of RISC-V SBI service implies a prior stage exists. As SBI
firmware usually passes a FDT to the loaded program, let's select
OF_HAS_PRIOR_STAGE if SBI is enabled.
With previously added fallback version of board_fdt_blob_setup, S-Mode
RISC-V ports use the SBI-provided FDT by default. This covers the most
common usecase, where a SPL (probably the U-Boot one) selects proper
devicetree, loads SBI and U-Boot then invokes SBI with the devicetree.
