The pseries platform already contains an IOMMU implementation, since it is
essential for the platform's paravirtualized VIO devices. This IOMMU
support is currently built into the implementation of the VIO "bus" and
the various VIO devices.
This patch converts this code to make use of the new common IOMMU
infrastructure.
We don't yet handle synchronization of map/unmap callbacks vs. invalidations,
this will require some complex interaction with the kernel and is not a
major concern at this stage.

Now that we're moving all of the device tree generation from an external
pre-execution generated blob to runtime generation using libfdt, we absolutely
must have libfdt around.
This requirement was there before already, as the only way to not require libfdt
with e500 was to not use -kernel, which was the only way to boot the mpc8544ds
machine. This patch only manifests said requirement in the build system.

Speeds up the build.
xilinx_ethlite uses tswap32() and is thus target-dependent.
