Fully migrate parisc to the IO functions from lib/iomem_copy.c. In a recent patch the functions memset_io and memcpy_toio were removed, but the memcpy_fromio was kept, because for very short sequences it does half word accesses, whereas the functions in lib/iomem_copy.c do byte accesses until the memory is naturally aligned and then do machine word accesses. But I don't think the single half-word access merits keeping the arch specific implementation, so, remove it as well.
