Will Deacon 81bb5c6420 arm64: locks: patch in lse instructions when supported by the CPU ...

On CPUs which support the LSE atomic instructions introduced in ARMv8.1,
it makes sense to use them in preference to ll/sc sequences.

This patch introduces runtime patching of our locking functions so that
LSE atomic instructions are used for spinlocks and rwlocks.
