arm64/hugetlb: Use macros for contiguous huge page sizes
Replace all open encoded contiguous huge page size computations with
available macro encodings CONT_PTE_SIZE and CONT_PMD_SIZE. There are other
instances where these macros are used in the file and this change makes it
consistently use the same mnemonic.
