Since the mvebu-mbus driver doesn't yet have a DT binding (and this DT
binding may not necessarily be ready for 3.11), the physical address
of the mvebu-mbus registers are currently hardcoded. This doesn't play
well with the fact that the internal registers base address may be
different depending on the bootloader.
In order to have only one central place for the physical address of
the internal registers, we now use of_translate_address() to translate
the mvebu-mbus register offsets into the real physical address, by
using DT-based address translation. This will go away once the
mvebu-mbus driver gains a proper DT binding.

Now that we have removed the need of the static I/O mapping for early
initialization reasons, and fixed the registers area length that were
broken, we can get rid of the static I/O mapping. Only the earlyprintk
mapping needs to be set up, using the debug_ll_io_init() helper
function.

In order to be able to support the LPAE, the internal registers
virtual base must be aligned to 2MB. In LPAE section size is 2MB, in
earlyprintk we map the internal registers and it must be section
aligned.

The changes needed to migrate the mach-mvebu (Armada 370 and Armada
XP) to the mvebu-mbus driver are fairly minimal, since not many
devices currently supported on those SoCs use address decoding
windows. The only one being the BootROM window, used to bring up
secondary CPUs.
However, this BootROM window needed for SMP brings an important
requirement: the mvebu-mbus driver must be initialized at the
->early_init() time, otherwise the BootROM window cannot be setup
early enough to be ready before the secondary CPUs are started.

This patch enhances the IRQ controller driver to add support for
Inter-Processor-Interrupts that are needed to enable SMP support.

This branch had quite a few conflicts, in particular with the PCI static
map rework from Rob Herring, and a few other context conflicts due to
changes in Kconfig, etc.
I fixed up conflicts in:
