riscv: correct pt_level name via pgtable_l5/4_enabled
The pt_level uses CONFIG_PGTABLE_LEVELS to display page table names.
But if page mode is downgraded from kernel cmdline or restricted by
the hardware in 64BIT, it will give a wrong name.
Like, using no4lvl for sv39, ptdump named the 1G-mapping as "PUD"
that should be "PGD":
0xffffffd840000000-0xffffffd900000000 0x00000000c0000000 3G PUD D A G . . W R V
So select "P4D/PUD" or "PGD" via pgtable_l5/4_enabled to correct it.
