The flag MPIC_WANTS_RESET shouldn't be set if we are doing cooperative
asymmetric MP. The second linux shouldn't reset the pic or the first
one gets very confused.

The Freescale implementation of MPIC only allows a single CPU destination
for non-IPI interrupts. We add a flag to the mpic_init to distinquish
these variants of MPIC. We pull in the irq_choose_cpu from sparc64 to
select a single CPU as the destination of the interrupt.
This is to deal with the fact that the default smp affinity was
changed by commit 1840475676 ("genirq:
Expose default irq affinity mask (take 3)") to be all CPUs.

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
3fd4473: powerpc/fsl: update crypto node definition and device tree
instances).

- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied.
- RTC quirk applies to all boards though, so no machine_is() checks.

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.

The interrupt routing in the device trees for the ULI M1575 was
inproperly using the interrupt line field as pci function. Fixed
up the device tree's to actual conform for to specification and
changed the interrupt mapping code so it just uses a static mapping
setup as follows:
PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9
USB 1.1 OCHI (1c.2) - IRQ10
USB 1.1 ECHI (1c.3) - IRQ11
LAN (1b.0) - IRQ6
AC97 (1d.0) - IRQ6
Modem (1d.1) - IRQ6
HD Audio (1d.2) - IRQ6
SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15
Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.
Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.
Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.
