fff69fd03d powerpc/83xx: factor out the common codes of setup arch functions
Factor out the common codes of setup arch functions to a separate
function. It does make no sense to print a board specific info
in setup arch functions, so use a more general one.

For ASP8347E board, there is no pci device node. So it is safe to
invoke mpc83xx_setup_pci() in its setup arch function even there is
no such invocation in its original setup arch function.

5657138404 powerpc: Move 32-bit probe() machine to later in the boot process
This converts all the 32-bit platforms to use the expanded device-tree
which is a pretty mechanical change. Unlike 64-bit, the 32-bit kernel
didn't rely on platform initializations to setup the MMU since it
sets it up entirely before probe_machine() so the move has comparatively
less consequences though it's a bigger patch.

bede480d45 powerpc/83xx: merge PCI bridge additions
Nearly all mpc83xx-based boards have a common piece of code - one that
loops over all pci/pcie bridges and registers them. Merge that code into
a special function common to all boards.

7669d58c66 powerpc/83xx: consolidate of_platform_bus_probe calls
83xx board files have a lot of duplication in
*_declare_of_platform_devices() functions. Merge that into a single
function common to most of the boards.

The only leftover is mpc834x_itx.c board file which explicitly asks for
fsl,pq2pro-localbus, as corresponding bindings don't provide
"simple-bus" compatibility in localbus node.

- Add timer (FSL GTM) node;
- Add gpio-controller node for BCSR13 bank (GPIOs on that bank
  are used to control the USB transceiver);
- Set up other BCSR registers;
- Configure the QE Par IO.

The work is loosely based on Li Yang's patch[1], which was used
to support peripheral mode only.

cccd21027c [POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascading
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.

3c5ede8cc6 [POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms with QE UEC"
This reverts commit 3baee95595.

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 77926826f3:

 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.
