One with a totally awkward API requiring the user having to know about
the underlying TLB organization.  A better implementation wouldn't be
hard to do, for anything that's outside of KSEG1's address range grab
a new TLB entry if needed and wire an entry into it.  Use the same
API as good old ioremap() and call the result early_ioremap().
