cpufreq: use kzalloc() to allocate memory for cpufreq_frequency_table
Few drivers are using kmalloc() to allocate memory for frequency tables and since we will have an additional field '.flags' in 'struct cpufreq_frequency_table', these might become unstable. Better get these fixed by replacing kmalloc() by kzalloc() instead. Along with that we also remove use of .driver_data from SPEAr driver as it doesn't use it at all. Also, writing zero to .driver_data is not required for powernow-k8 as it is already zero. Reported-and-reviewed-by: Gautham R.
