Ira Weiny 7438f36310 parisc/kmap: remove duplicate kmap code

parisc reimplements the kmap calls except to flush its dcache.  This is
arguably an abuse of kmap but regardless it is messy and confusing.

Remove the duplicate code and have parisc define ARCH_HAS_FLUSH_ON_KUNMAP
for a kunmap_flush_on_unmap() architecture specific call to flush the
cache.
