[PATCH 4/5] riscv/spike: Change the default bios to use generic platform image

[Bin Meng]

From: Bin Meng <address@hidden>

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.
