sh64: Kill off unused fixed I/O mapping window.
This was reworked some time ago to go through fixmaps instead, leaving the range itself unused. As such, kill off the remaining references and hand over the remaining space for fixmaps directly. This also makes it possible to simplify the vmalloc fault case as we no longer have to care about the special section. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
