    V4L/DVB (3384): Separate tv & radio freqs, fix cb/freq transmit order for tuners that need this. · 27487d44

    - Moved MSP_SET_MATRIX to v4l2-common.h
    - Fix typos and integer overflows in tea5767.c
    - Split old freq field into a tv_freq and a radio_freq. Prevents
      that a radio tuner is initialized with a tv frequency or vice versa.
    - When switching to radio mode initialize the tuner with the last
      used radio frequency (this was already done for the TV mode).
      As a result of these changes the tuner module now remembers the
      last set radio and TV frequencies, which is what you would expect
      to happen.
    - Move out of range frequencies to the closest valid frequency as per
      v4l2 API spec.
    - Fix incorrect initial radio frequency (multiplier is 16000, not 16)
    - Add boundary check for out of range frequencies.
    - Use new flag to check if the order of the CB and freq. depends on
      the last set frequency. That is needed for some tuners or you can
      get static as a result. The flag is added for those tuners where I know
      that the datasheet indicates that this is necessary.
    - For this new check use the last set div value, not the last frequency
      as radio frequencies are always much higher due to the 16000 multiplier.
