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.
