[PATCH 4/5] 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 keeping ELF
files here was intentional.
