cpufreq: pxa: make pxa_freqs arrays const
pxa255_run_freqs and pxa255_turbo_freqs are only read. This patch updates arrays declaration, find_freq_tables() and its callsites. Suggested-by: Joe Perches <joe@perches.com> Signed-off-by: Fabian Frederick <fabf@skynet.be> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
