locking/atomics/arm64: Replace our atomic/lock bitop implementations with asm-generic
The <asm-generic/bitops/{atomic,lock}.h> implementations are built around the atomic-fetch ops, which we implement efficiently for both LSE and LL/SC systems. Use that instead of our hand-rolled, out-of-line bitops.S.
