14bdc9132e powerpc/85xx: fix various PCI node compatible strings
Fix and/or improve the compatible strings of the PCI device tree nodes for
some Freescale SOCs.  This fixes some issues and improves consistency among
the SOCs.

Specifically:

1) The P1022 has a v1 PCIe controller, so the compatible property should just
say "fsl,mpc8548-pcie".  U-Boot does not look for "fsl,p1022-pcie", so it
wasn't fixing up the node.

2) The P4080 has a v2.1 PCIe controller, so add that version-specific string
to the device tree.  Update the kernel to also look for that string.
Currently, the kernel looks for "fsl,p4080-pcie" specifically, but
eventually that check should be deleted.

3) The P1010 device tree claims compatibility with v2.2 and v2.3, but that's
redundant.  No other device tree does this.  Remove the v2.2 string.

4) The kernel looks for both "fsl,p1023-pcie" and "fsl,qoriq-pcie-v2.2",
even though the P1023 device trees has always included both strings.  Remove
the search for "fsl,p1023-pcie".

0408753fae powerpc/85xx: describe the PAMU topology in the device tree
The PAMU caches use the LIODNs to determine which cache lines hold the
entries for the corresponding LIODs.  The LIODNs must therefore be
carefully assigned to avoid cache thrashing -- two active LIODs with
LIODNs that put them in the same cache line.

Currently, LIODNs are statically assigned by U-Boot, but this has
limitations.  LIODNs are assigned even for devices that may be disabled
or unused by the kernel.  Static assignments also do not allow for device
drivers which may know which LIODs can be used simultaneously.  In
other words, we really should assign LIODNs dynamically in Linux.

To do that, we need to describe the PAMU device and cache topologies in
the device trees.

b9db022c62 powerpc/85xx: Rework P4080DS device trees
Utilize new split between board & SoC, and new SoC device trees split
into pre & post utilizing 'template' includes for SoC IP blocks.

Other changes include:
* Adding of MPIC timer blocks
* Dropping "fsl,p4080-IP..." from compatibles for standard blocks
* Removed mpic interrupt-parent from dcsr-epu node, just use top level
* Removed mpic interrupt-parent from sec nodes, just use top level
