target/ppc: Check page dir/table base alignment
According to PowerISA 3.1B, Book III 6.7.6 programming note, the
page directory base addresses are expected to be aligned to their
size. Real hardware seems to rely on that and will access the
wrong address if they are misaligned. This results in a
translation failure even if the page tables seem to be properly
populated.
