The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core. It only is useful
for cpufreq drivers for their internal purposes.
Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.
Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

gcc-3.8 correctly found that the variables set by find_freq_tables()
are not initialized if this function is called on something other
than a pxa2xx or pxa3xx:
pxa2xx-cpufreq.c: In function 'pxa_verify_policy':
pxa2xx-cpufreq.c:272:6: warning: 'pxa_freqs_table' may be used uninitialized in this function [-Wmaybe-uninitialized]
pxa2xx-cpufreq.c: In function 'pxa_set_target':
pxa2xx-cpufreq.c:345:23: warning: 'pxa_freq_settings' may be used uninitialized in this function [-Wmaybe-uninitialized]
Rather than adding a bogus initialization that would let us
get a little further before crashing, add an explicit BUG().
We know that this code is designed to run on only these cpus,
so this will fix the build warning and give a more helpful
diagnostic if the code ever changes to run on other machines.
