V4L/DVB (3214): Calculate the saa7115 AMCLK regs instead of using fixed values
- Calculate the audio master clock registers from the actual
frequencies. This simplifies the code and it also prepares
for adding CGC2 support.
- VIDIOC_INT_AUDIO_CLOCK_FREQ now receives an u32 instead of
an enum. It is more generic and actually easier to implement.
