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.
