Split out the logic that allocates a struct iommu into a separate
function. This can fail however the calling code has never cared - so
just return if we can't allocate an iommu.

In order to support the fixed IOMMU mapping (in a subsequent patch),
we need the hash table to be inside the IOMMUs DMA window. This is
usually 2G, but let's make sure the hash table is under 1G as that
will satisfy the IOMMU requirements and also means the hash table will
be on node 0.

The use of the __GENERIC_PERCPU is a bit problematic since arches
may want to run their own percpu setup while using the generic

The break_lock data structure and code for spinlocks is quite nasty.
Not only does it double the size of a spinlock but it changes locking to
a potentially less optimal trylock.
Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a
__raw_spin_is_contended that uses the lock data itself to determine whether
there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is
not set.
Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to
decouple it from the spinlock implementation, and make it typesafe (rwlocks
do not have any need_lockbreak sites -- why do they even get bloated up
with that break_lock then?).

This patch converts the remaining 83xx boards to the dts-v1 format.
This includes the mpc8313_rdb, mpc832x_mds, mpc8323_rdb, mpc8349emitx,
mpc8349emitxgp and the mpc836x_mds.
The mpc8315_rdb mpc834x_mds, mpc837[789]_*, and sbc8349 were already
dts-v1 and only undergo minor changes for the sake of formatting
consistency across the whole group of boards; i.e. the idea being
that you can do a "diff -u board_A.dts board_B.dts" and see something
meaningful.
The general rule I've applied is that entries for values normally
parsed by humans are left in decimal (i.e. IRQ, cache size, clock
rates, basic counts and indexes) and all other data (i.e. reg and
ranges, IRQ flags etc.) remain in hex.
I've used dtc to confirm that the output prior to this changeset
matches the output after this changeset is applied for all boards.

Currently there are several dts that don't specify address or size
cells for the muram. This causes dtc to use default values, one of
which is an address-cells of two, and this breaks the parsing of the
muram ranges, which is assuming an address-cells of one. For example:
Warning (reg_format): "reg" property in
/qe@e0100000/muram@10000/data-only@0 has invalid length
(8 bytes) (#address-cells == 2, #size-cells == 1)
Explicitly setting the address and size cells gets it parsed properly
and gets rid of the four dtc warnings.
