Will Deacon 084f903727 arm64: bitops: 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 bitops functions so that
LSE atomic instructions are used instead.
