Define ptdesc_t type which describes the basic page table descriptor layout on arm64 platform. Subsequently all level specific pxxval_t descriptors are derived from ptdesc_t thus establishing a common original format, which can also be appropriate for page table entries, masks and protection values etc which are used at all page table levels.
