ARM: improve compiler's ability to optimize page tables

Allow the compiler to better optimize the page table walking codeby avoiding over-complex pmd_addr_end() calculations. Thesecalculations prevent the compiler spotting that we'll never iterateover the PMD table, causing it to create double nested loops wherea single loop will do.
