MTHCA_RESET_VALUE must always be swapped, since the HCA expects to see
it in big-endian order and we write it with writel.  This means on
little-endian systems we have to swap it to big-endian order before
writing, and on big-endian systems we need to swap it to make up for
the additional swap that writel will do.  This fixes resetting the HCA
on big-endian machines.
