core: tee_mmu_check_access_rights() check all pages
Prior to this patch tee_mmu_check_access_rights() checks an address in each page of a supplied range. If both the start and length of that range is unaligned the last page in the range is sometimes not checked. With this patch the first address of each page in the range is checked to simplify the logic of checking each page and the range and also to cover the last page under all circumstances.
