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.

The RaidEngine is a new Freescale hardware that used for parity
computation offloading in RAID5/6.
This patch adds the device node in device tree and related binding
documentation.

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,p5020-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
