[PATCH 006/228] 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 doesn't stays much readable..
Lets use bitwise shift operator << to generate these numbers for respective
positions.
