arm64: Use level-2 for largest block mappings when FEAT_HAFDBS is present

In order to make invalidation by VA more efficient, set the largest
block mapping to 2MB, mapping it onto level-2. This has no material
impact on u-boot's runtime performance, and allows a huge speedup
when cleaning the cache.
