The "using cpu_has_llsc cleanup all users of ll/sc and lld/scd." broke

Clearly a kernel bug - but one that also shows poor maintenance of your
target. It should define cpu_has_llsc which it doesn't, so the kernel
will use generic code and deciede at runtime it should use ll/sc. I'm
fixing this problem but you really should fix your target also.
