powerpc/pseries: Fix build break due to pnv_npu2_init()

Commit 3be2df00e299 ("powerpc/pseries/npu: Enable platform support")
added a call to pnv_npu2_init() in pseries code. This causes a build
break if we build with CONFIG_PPC_PSERIES && !CONFIG_PPC_POWERNV:

  powerpc64le-pc-linux-gnu-ld: arch/powerpc/platforms/pseries/pci.o: in function `pSeries_final_fixup':
  pci.c:(.init.text+0x1b0): undefined reference to `pnv_npu2_init'

This commit therefore wraps that line in an ifdef, so that pseries
builds without powernv.
