Blackfin: add new cacheflush syscall
Flushing caches sometimes requires anomaly workarounds which require
supervisor-only insns. Normally we don't need to flush caches from
userspace so this isn't a problem, but when gcc generates trampolines
on the stack, we do.
So add a new syscall for gcc to use modeled after the mips version.
