ixp4xx-kernel: improve fixup patches, remove loft one, add cmdline byteswap in 2.6.15

 - the fixup patches for NSLU2 and NAS100D have been slightly simplified.
   the fixup for Loft has been removed, it isn't useful.
   code in arch/arm/kernel/setup.c to automagically swap the command line
   has been added in 48-setup-byteswap-cmdline.patch
