Subject: [PATCH kernel v4 03/11] powerpc/powernv: Rename pnv_pci_ioda2_tce_invalidate_entire

As in fact pnv_pci_ioda2_tce_invalidate_entire() invalidates TCEs for
the specific PE rather than the entire cache, rename it to
pnv_pci_ioda2_tce_invalidate_pe(). In later patches we will add
a proper pnv_pci_ioda2_tce_invalidate_entire().
