[PATCH v2] powerpc/4xx: DTS: Add Add'l SDRAM0 Compatible and Interrupt Info

[Grant Erickson <gerickson@nuovations.com>]

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.

Signed-off-by: Grant Erickson <gerickson@nuovations.com>
---
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.
