add simple-bus compatible property to soc nodes for 83xx/85xx platforms
that were missing them.  Add same to platform probe code.

This fixes SoC device drivers (such as talitos) to succeed in matching
devices present in the soc node.

also update mpc836x_rdk dts to new SEC bindings (overlooked in commit
3fd44736: powerpc/fsl: update crypto node definition and device tree
instances).

asm-powerpc/mpc85xx.h was really a hold over from arch/ppc.  Now that
more decoupling has occurred we can remove <asm/mpc85xx.h> and some of
its legacy.

As part of this we moved the definition of CPM_MAP_ADDR into cpm2.h
for 85xx platforms.  This is a stop gap until drivers stop using
CPM_MAP_ADDR.

On the majority of 85xx & 86xx we have a register that's ability to
assert HRESET_REQ to reset the board.  We refactored that code so it
can be shared between both platforms into fsl_soc.c and removed all
the duplication in each platform directory.

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.

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
are going to use down to the pci_exclude_device function. This will
greatly simplify being able to exclude the PHBs in multiple controller
setups.

When CONFIG_PCI is disabled, the definitions for isa_io_base,
isa_mem_base and pci_dram_offset are entirely unused, but they
can result in link failure because they are defined in multiple
places.

The easiest fix is to just remove all these definitions.

This patch reworks the way IRQs are fixed up on PCI for arch powerpc.

It makes pci_read_irq_line() called by default in the PCI code for
devices that are probed, and add an optional per-device fixup in
ppc_md for platforms that really need to correct what they obtain
from pci_read_irq_line().

It also removes ppc_md.irq_bus_setup which was only used by pSeries
and should not be needed anymore.

I've also removed the pSeries s7a workaround as it can't work with
the current interrupt code anyway. I'm trying to get one of these
machines working so I can test a proper fix for that problem.

I also haven't updated the old-style fixup code from 85xx_cds.c
because it's actually buggy :) It assigns pci_dev->irq hard coded
numbers which is no good with the new IRQ mapping code. It should
at least use irq_create_mapping(NULL, hard_coded_number); and possibly
also set_irq_type() to set them as level low.

This makes the 8560 evaluation board fully supported under arch/powerpc,
as the first board with CPM2 SoC peripherals. The brand new devicetree
nodes are introduced (intending to be a subset of the QuiccEngine-equipped
models, with dts sources placed into the kernel according to the new convention.

Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART
update), the both TSEC eth ,FCC Eths, and both SCC UARTs are
working. The relevant drivers are still capable to drive users in ppc,
which was verified with 8272ADS (SCC uart+FCC eth).

This is also verified on mpc8540 and actually make it work (PCI stuff
working as well)

sub-arch's and make the board's probe() functions actually do something.
