arch/riscv: Pass the bootrom-provided FDT to the payload
The RISC-V boot protocol foresees that at every stage boundary (bootrom
to boot loader, boot loader -> OS), register a0 contains the Hart ID and
a1 contains the physical address of the Flattened Device Tree that the
stage shall use.
As a first step, pass the bootrom-provided FDT to the payload,
unmodified.
