MIPS: mm: c-r4k: Flush scache to avoid cache aliases
There is a chance for the secondary cache to have memory aliases. This can happen if the bootloader is in a non-EVA mode (or even in EVA mode but with different mapping from the kernel) and the kernel switching to EVA afterwards. It's best to flush the icache to avoid having the secondary CPUs fetching stale data from it.
