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.

Now that the generic code doesn't assign resources for Freescale
PHBs we dont have to explicitly exclude it.

Remove includes of files that existed in arch/ppc that we dont need in
arch/powerpc anymore.  The following includes were removed:

 <asm/amigappc.h>
 <asm/bootinfo.h>
 <asm/ppcboot.h>
 <asm/ppc_sys.h>
 <asm/residual.h>
 <asm/m8260_pci.h>

This also caused platforms/embedded6xx/mpc7448_hpc2.h to no longer be
needed and thus removed.

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.

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.

Many platforms currently define their own add_bridge function, some
of them globally. This breaks some multiplatform configurations.
Prefixing each of these functions with the platform name avoids

Incorrect use of of_find_node_by_name() causes of_node_put()

These were inherited from ARCH=ppc, but are not needed since parsing of interrupts
should be done via the of_* functions (who can do swizzling). If we ever need to
do non-standard swizzling on bridges without a device-node, then we might add
back a slightly different version of ppc_md.pci_swizzle but for now, that is not
the case.

I removed the couple of calls for these in 83xx. If that breaks something, then
there is a problem with the device-tree on these.
