These are the actual frequencies reported by the PLL, so let's
report these. The roundoffs are inappropriate, we should round
to the frequency that the clock will later report.
Drop some whitespace at the same time.

There was an "unknown" firmware variant turning up in the wild
causing problems in the clock driver. Add this missing variant
and clarify that varian 11 and 15 are Samsung variants, as this
is now very well known from released products.

Clock maintainers: could you please ACK this so Lee can take
this into the MFD tree? The chances of merge collisions are
zero, this code changes very seldom.

Actually I intended for the clock people to ACK it for you
but since it is completely independent of 1/2 it actually works
either way, maybe they will rather pick it up, who knows? :D

That's fine too.
I assume they will not require an immutable branch, as the turn-over
in this file is very low.

Seems fine to go through mfd. Isn't there some other ux500 patch on the
list though?

Not for clocking, maybe more MFD stuff so merging to MFD should be
the best option.
