docs: explain effect of smp_read_barrier_depends() on modern architectures
The documentation for smp_read_barrier_depends() does not mention the architectures
for which it is an optimization, for example ARM and PPC. As a result, it is not
clear to the reader why one would use it. Relegate Alpha to a footnote together
with other architectures where it is equivalent to smp_rmb().
