[PATCH v2 5/7] hw/riscv: spike: Change the default bios to use generic platform image

[Bin Meng <bmeng.cn@gmail.com>]

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

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

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