m68k: use io_no.h for MMU and non-MMU enabled ColdFire Use the io_no.h IO access support for all ColdFire systems, no matter whether configured with MMU enabled or disabled. Previously there was subtle differences in IO access functions used in both cases, and these resulted in broken behavior for some drivers. As observed and reported by Angelo when using MMU enabled systems the read/write family of functions was using little endian access, while the non-MMU enabled systems were using native endian. This results in drivers that are shared across Freescale processors (for some of the common internal SoC peripherals) not working - since they are wired up for native endian access. This problem brings to light issues with PCI bus access and local peripheral access - but these are not addressed with this fix.
