[PATCH 1/8] powerpc/firmware: Add definitions for new firmware features.

[Michael Bringmann]

Firmware Features: Define new bit flags representing the presence of
new device tree properties "ibm,drc-info", and "ibm,dynamic-memory-v2".
These flags are used to tell the front end processor when the Linux
kernel supports the new properties, and by the front end processor to
tell the Linux kernel that the new properties are present in the devie
tree.
