[PATCH v6 5/6] hw/riscv: spike: Change the default bios to use generic platform image

[Bin Meng]

From: Bin Meng <bin.meng@windriver.com>

To keep sync with other RISC-V machines, change the default bios to
use generic platform fw_dynamic.elf image.

While we are here, add some comments to mention that using ELF files
for the Spike machine was intentional.
