Intuitively, higher page table levels should have smaller enum values, but PTE is currently assigned 0. For consistency and cleanup, reverse the enum value ordering. Since there is no current user relies on these numbers to be ascending from PTE->PGD, so it can be changed to be ascending from PGD->PTE, in the direction of the page table walk.
