cpufreq: rewrite cpufreq_driver->flags using shift operator
Currently cpufreq_driver's flags are defined directly using 0x1, 0x2, 0x4, 0x8, etc.. As the list grows it becomes less readable.. Use bitwise shift operator << to generate these numbers for respective positions. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Reviewed-by: Srivatsa S.
