This adds the basic support for the Wind River SBC834x boards.  The
SBC8349 is more common, although it should work on the SBC8347 board
as well.  Support is heavily based on the existing MPC834x_MDS code.

This adds to the 32 bits PCI code some flags, replacing the old
pci_assign_all_busses global, that allow us to control various
aspects of the PCI probing, such as whether to re-assign all
resources or not, or to not try to assign anything at all.

This also adds the flag x86 already has to avoid ISA alignment
on bridges that don't have ISA forwarding enabled (no legacy
devices on the top level bus) and sets it for PowerMacs.

currently the board-level PHY reset code for the mpc832x MDS messes with

looks like this board code was cut-n-pasted from the mpc8360 mds code,
which has the PHY reset bits in a different BCSR); this patch points

set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.

To solve this problem efficiently, QEIC needs pluggable handlers,
specific to the underlaying interrupt controller.

Patch extends qe_ic_init() function to accept low and high interrupt
handlers. To avoid #ifdefs, stack of interrupt handlers specified in
the header file and functions are marked 'static inline', thus
handlers are compiled-in only if actually used (in the board file).
Another option would be to lookup for parent controller and
automatically detect handlers (will waste text size because of
never used handlers, so this option abolished).

qe_ic_init() also changed in regard to support multiplexed high/low
lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic()
handler implemented appropriately.

On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete
bridges (mpc10x, tsi108) use the new for_each_compatible_node() or
for_each_node_by_type() to provide more exact matching when looking for
PHBs in the device tree.

With the previous code it was possible to match on pci bridges since
we were only matching on device_type.

This reverts commit 3baee955.

That commit was a mistake from the start; I added mdio type to the
bus scan list early on in my ucc_geth migrate to phylib development,
which is just pure wrong (the ucc_geth_mii driver creates the mii
bus and the PHY layer handles PHY enumeration without translation).

This follows on from commit 77926826:

 Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"

which was basically trying to hide a symptom of the original mistake
this revert fixes.

to handle topologies with P2P bridges well so we let Linux just reassign

There are times that we need to know which controller we are on to decide
how to exclude devices properly.  We now pass the pci_controller that we

setups.
