[PATCH v3] powerpc/4xx: DTS: Add Add'l SDRAM0 Compatible and Interrupt Info

[Grant Erickson]

Added additional information for type and compatibility strings and
interrupt information to the SDRAM0 memory-controller device tree
nodes for AMCC PowerPC 405EX[r]-based boards to facilitate binding
with the new "ibm,sdram-4xx-ddr2" EDAC memory controller adapter driver.

As support in the associated EDAC adapter driver is added over time,
similar changes will/should be made to the DTS files for boards
leveraging realizations of this "ibm,sdram-4xx-ddr2" controller,
including the 440SP, 440SPe, 460EX, 460GT and 460SX.

Patch v2, based on review from David Gibson, removes the 'device_type'
field because it is only used for legacy OpenFirmware method
interfaces and no such compatibility is warranted here. In addition,
removed address- and size-cells as this node has no children.

Patch v3, based on review from Josh Boyer and Stefan Roese, simplifies
the interrupt specification because both the SEC and DED interrupts
are mapped to the same interrupt parent.
