drm: Promote drm_mm alignment to u64
In places (e.g. i915.ko), the alignment is exported to userspace as u64
and there now exists hardware for which we can indeed utilize a u64
alignment. As such, we need to keep 64bit integers throughout when
handling alignment.
Testcase: igt/drm_mm/align64
Testcase: igt/gem_exec_alignment
