[PATCH 00/13] IXP4xx spring cleaning

This cleans out the remaining board files from IXP4xx and
makes it an exclusive device tree subarchitecture without any
special weirdness in arch/arm/mach-ixp4xx.
The biggest noticeable change is the removal of the old PCI
driver and along with that the removal of the special DMA
coherency code and defines and the DMA bouncing.
I tried to convert the IXP4xx to multiplatform on top of
this but it didn't work because IXP4xx wants to be big
endian and multiplatform config creates a problem like
this:
../arch/arm/kernel/head.S: Assembler messages:
../arch/arm/kernel/head.S:94: Error: selected processor does not support `setend be' in ARM mode
I think this is because MULTI_V5 turns on CPUs that cannot
do big endian, and IXP4xx turn on big endian. (It crashes if
I try to boot in little endian mode, sorry. It really wants
to run big endian.)
But before fixing multiplatform we can fix all of this!
The networking patches are dependencies so I am requesting
ACKs from the network maintainers on these.
