parisc: fix compile failure with kmap_atomic changes 

Commit 3e4d3af501 ("mm: stack based kmap_atomic()") overlooked the
fact that parisc uses kmap as a coherence mechanism, so even though we
have no highmem, we do need to supply our own versions of kmap (and
atomic).  This patch converts the parisc kmap to the form which is
needed to keep it compiling (it's a simple prototype and name change).
