Enable atomic swap and store macro with acquire and release ordering
Add atomic swap and store macro with acquire and release ordering
respectively. Variable in question is interupt_pending variable which
is used as guard variable by input nodes to process the device queue.
Atomic Swap is used with Acquire ordering as writes or reads following
this in program order should not be reordered before the swap.
Atomic Store is used with Release ordering, as post store the node is
added to pending list.
