Soby Mathew c97cba4ea4 Fix the CAS spinlock implementation Make the spinlock implementation use ARMv8.1-LSE CAS instruction based on a platform build option. The CAS-based implementation used to be unconditionally selected for all ARM8.1+ platforms. The previous CAS spinlock implementation had a bug wherein the spin_unlock() implementation had an `sev` after `stlr` which is not sufficient. A dsb is needed to ensure that the stlr completes prior to the sev. Having a dsb is heavyweight and a better solution would be to use load exclusive semantics to monitor the lock and wake up from wfe when a store happens to the lock. The patch implements the same.
