[PATCH 0/4] ARM: footbridge: cleanups

I had an older patch to remove the addin mode for footbridge,
which nobody is using any more, and I found a few other small
cleanups that are worth doing here.

Footbridge is now the only platform with a custom __virt_to_bus()
for ISA DMA, and a custom phys_to_dma() for PCI devices. Both
just add a fixed offset, so there is probably a better way
of doing the same without a custom helper function.
