   ath9k: Enable Fractional N mode

changed the hw attach code to fix up initialization values only for
dual band devices, however the commit message did not give a reason as
to why this would be useful or necessary.

According to tests by Jorge Boncompte, this breaks at least some
2GHz-only cards, so the code should be changed back to the
unconditional INI fixup.
