The pte_update() implementation for PPC_8xx unfolds page table from the PGD level to access a PMD entry. Since 8xx has only 2-level page table this can be simplified with pmd_off() shortcut. Replace explicit unfolding with pmd_off() and drop defines of pgd_index() and pgd_offset() that are no longer needed. Signed-off-by:
