tests with atime enabled, which ones?

Could we please be a little be less scary.

1. I think these starting and ending "*****" lines are unnecessary.
2. Ah, and use "UBIFS", not "Ubifs" please.
3. Let's be shorter, just this should be enough:

ubifs_warn("full atime support is enabled, which may wear out your
flash faster");
