Subject: [PATCH V3 1/2 linux-next] cpufreq: pxa: replace typedef pxa_freqs_t by structure

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).

Signed-off-by: Fabian Frederick <fabf@...net.be>

Compiled but untested.

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