parisc: fix map_pages() to actually populate upper directory
The commit d96885e277b5 ("parisc: use pgtable-nopXd instead of
4level-fixup") converted PA-RISC to use folded page tables, but it missed
the conversion of pgd_populate() to pud_populate() in maps_pages()
function. This caused the upper page table directory to remain empty and
the system would crash as a result.
Using pud_populate() that actually populates the page table instead of
dummy pgd_populate() fixes the issue.
