So uh, enabling atime is bad.
When atime tracking is enabled on a filesystem, simple read-only
operations result in touching the atime value, resulting in writes.
This is bad for both performance and flash lifetime.
Many historical Android devices have shipped with 'noatime' enabled,
so we're just bringing marlin/sailfish in alignment with them.
Test: booted, benchmarked before/after
