prom_init.c: Enable support for new DRC device tree properties
"ibm,drc-info" and "ibm,dynamic-memory-v2" in initial handshake
between the Linux kernel and the front end processor.
[V2: Revise constant names.]
[V3: No change.]
[V4: Update comments]
[V5: Resynchronize/resubmit]
[V6: Resynchronize to latest kernel commit code]
[V7: Correct mail threading]
[v8: Insert more useful variable names]
