video: pxafb: Remove cpufreq policy notifier
The cpufreq policy notifier's CPUFREQ_ADJUST notification is going to get removed soon. The notifier callback pxafb_freq_policy() isn't doing anything apart from printing a debug message on CPUFREQ_ADJUST notification. There is no point in keeping an otherwise empty callback and registering the notifier. Remove it.
