byteorder: use generic C version for value byteswapping
This makes the new implementation of the byteorder helpers match the old in how it degraded when an arch-defined version was not available: 1) swab() - look for arch defined - if not, use generic c version 2) swabp() - look for arch-defined - if not, deref pointer and use swab() 3) swabs() - look for arch defined - if not, use swabp Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Cc: "David S.
