[PATCH v5 20/42] powerpc/powernv: Rename pnv_ioda_get_pe() to pnv_ioda_dev_to_pe()

[Gavin Shan]

pnv_ioda_get_pe() indicates it's increasing refcount to the given
PE instance from the name. However, it gets the instance of the
PE, which contains the indicated PCI device. The patch renames it
to pnv_ioda_dev_to_pe() to reflect its purpose.
