parisc: Implement __smp_store_release and __smp_load_acquire barriers
commit e96ebd589debd9a6a793608c4ec7019c38785dea upstream.
This patch implements the __smp_store_release and __smp_load_acquire barriers
using ordered stores and loads. This avoids the sync instruction present in
the generic implementation.
