x86: remove byte locks
Impact: cleanup Remove byte locks implementation, which was introduced by Jeremy in 8efcbab6 ("paravirt: introduce a "lock-byte" spinlock implementation"), but turned out to be dead code that is not used by any in-kernel virtualization guest (Xen uses its own variant of spinlocks implementation and KVM is not planning to move to byte locks).
