locking/barriers: Replace smp_cond_acquire() with smp_cond_load_acquire() ...
This new form allows using hardware assisted waiting.
Some hardware (ARM64 and x86) allow monitoring an address for changes,
so by providing a pointer we can use this to replace the cpu_relax()
with hardware optimized methods in the future.
