[PULL 10/88] ppc/pnv: Link "chip" property to PnvCore::chip pointer

[David Gibson]

From: Greg Kurz <address@hidden>

The core object has both a pointer and a "chip" property pointing to the
chip object. Confusing bugs could arise if these ever go out of sync.

Change the property definition so that it explicitely sets the pointer.
