rS363222: [PowerPC] Use PVO_PADDR to get the PA from PVO

Summary

Use PVO_PADDR macro to get the physical address from a PVO, instead of explicitly ANDing pvo_pte.pa with LPTE_RPGN where it is needed.
Besides improving readability, this is needed to support superpages (D25237), where the steps to get the PA from a PVO are different.
