Some saa7115-based cards use a different crystal frequency and a different audio clock generation. Add a new VIDIOC_INT_S_CRYSTAL_FREQ command to be able to set these values. Also change the default APLL setting to 0. It makes no sense to have the audio clock independent from the video clock, this can lead to audio/video synchronization problems. Setting this to 0 is also consistent with the old saa7114.c source and the way the Hauppauge Windows driver sets it.
