[RFC PATCH v1 1/4] powerpc: apm82181: create shared dtsi for APM bluestone

This patch adds an DTSI-File that can be used by various device-tree
files for APM82181-based devices.
Some of the nodes (like UART, PCIE, SATA) are used by the uboot and
need to stick with the naming-conventions of the old times'.
I've added comments whenever this was the case. But unfortunately,
this I've to point out that for this reason, there are some warning
messages when compiling the dtb:
> apm82181.dtsi:440.26-483.5: Warning (pci_bridge): /plb/pciex at d00000000: node name is not "pci" or "pcie"
> wd-mybooklive.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge'
