    drivers/intel/gma/vbt: Add Kconfig symbol for SSC ref
    
    The selection of the SSC reference frequency for LVDS was based on a
    completely unrelated clock.
    
    The `ssc_freq` flag should be set when the SSC reference runs at a
    different frequency than the general display reference clock (DREF).
    For most platforms, there is no choice, i.e. for i945 and gm45 the SSC
    reference always differs from the display reference clock (i945: 66Mhz
    SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and
    newer, it's the same frequency for SSC/non-SSC (120MHz).  The only,
    currently supported platform with a choice seems to be Pineview, where
    the alternative is 100MHz vs. the default 96MHz.
