powerpc/mm: Standardise pte_update() prototype between PPC32 and PPC64
PPC64 takes 3 additional parameters compared to PPC32:
- mm
- address
- huge
These 3 parameters will be needed in order to perform different
action depending on the page size on the 8xx.
Make pte_update() prototype identical for PPC32 and PPC64.
This allows dropping an #ifdef in huge_ptep_get_and_clear().
