You should be including pnv-pci.h here.

Otherwise the header and the implementation could get out of sync, it will also
fix these:

  arch/powerpc/platforms/powernv/pci-ioda.c:1365:5: warning: symbol 'pnv_phb_to_cxl' was not declared. Should it be static?
  arch/powerpc/platforms/powernv/pci-ioda.c:1389:5: warning: symbol 'pnv_cxl_alloc_hwirqs' was not declared. Should it be static?
