typedef is not really useful here. Replace it by structure
to improve readability. typedef should only be used in some cases.
(See Documentation/CodingStyle Chapter 5 for details).

Compiled but untested.

V3: -constify arrays(patch 2) (suggested by Joe Perches)
    -fix typo in changelog (thanks to Viresh Kumar)
V2: -verbose changelog.

pxa255_run_freqs and pxa255_turbo_freqs are only read.
This patch updates arrays declaration, find_freq_tables()
and its callsites.
