This reverts commit
6cebf17929c8b8de217babe7d7cd7f45550cff41.
The earlier patch tried to enable support for a new property
"ibm,drc-info" on powerpc systems.
Unfortunately, some errors in the associated patch set break things
in some of the DLPAR operations. In particular when attempting to
hot-add a new CPU or set of CPUs, the original patch failed to
properly calculate the available resources, and aborted the operation.
In addition, the original set missed several opportunities to compress
and reuse common code.
As the associated patch set was meant to provide an optimization of
storage and performance of a set of device-tree properties for future
systems with large amounts of resources, reverting just restores
the previous behavior for existing systems. It seems unnecessary
to enable this feature and introduce the consequent problems in the
field that it will cause at this time, so please revert it for now
until testing of the corrections are finished properly.
