drivers/intel/gma: Ditch `link_frequency_270_mhz` setting
The `link_frequency_270_mhz` setting was originally used by the native
graphics init code for Sandy/Ivy Bridge, which is long gone.
The value of this information (which board had it set) is questionable.
The only board that had an LVDS panel and set it to 0 was the ThinkPad
L520, where native graphics init was never reported to work. Also, the
native graphics init only used it for calculations, but never confi-
gured the hardware to use a specific frequency. A look into the docu-
mentation also doesn't reveal any straps that could be used to confi-
gure it.
