arm64: Reduce PT size estimation complexity count_required_pts()'s complexity is high if mappings are not using the largest possible block size (due to some other requirement such as tracking dirty pages, for example). Let's switch to a method that follows the pattern established with the add_map() helper, and make it almost instantaneous instead of taking a large amount of time if 2MB mappings are in use instead of 1GB.
