Don't these clocks fit in 100 chars?

A space is missing before "xo".

We typically list them on one line each, so I'm fine with that.
But all three clocks should be aligned.

These two clocks can fit in 100 chars but we have 3 clocks they don't
fit in 100 chars.

Was about to push out my branch of patches, but before I do. Can you
please describe WHY this is needed?

We are making use of this clock in dll register value calculation,
The default PoR value is also same as calculated value for
HS200/HS400/SDR104 modes.
But just not to rely on default register values we need this entry.
