Subject: [PATCH 4.14 075/239] of: make PowerMac cache node search conditional on CONFIG_PPC_PMAC

From: Rob Herring <robh@...nel.org>

[ Upstream commit f6707fd6241e483f6fea2caae82d876e422bb11a ]

Cache nodes under the cpu node(s) is PowerMac specific according to the
comment above, so make the code enforce that.
