parisc: iomap: introduce io{read|write}64

Browse Source 
Add support for io{read|write}64() functions in parisc architecture.
These are pretty straightforward copies of similar functions which
make use of readq and writeq.

Also, indicate that the lo_hi and hi_lo variants of these functions
are not provided by this architecture.
