powerpc/4xx: DTS: Add Add'l SDRAM0 Compatible and Interrupt Info

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.
