sh: pass through ioremap() for non-mmu processors.
All 32-bit SuperH processors currently go through __ioremap_mode()
and check for IO_TRAPPED and directly mapped segments. With this
patch we simplify the MMU less case with a pass through version of
__ioremap_mode() which just returns the physical address.
The effects of this is change are:
- fix non-MMU ioremap() of high address hardware blocks (sh7203 CMT)
- make sure IO_TRAPPED is not selected
