drm/i915/glk: Remove 99% limitation.

While checking the opportunity to add a display_gen
check to allow glk and cnl to be on same bucket I noticed
these FIXME cases here.

So I got the confirmation from HW architect that we actually
never needed this workaround.

"GLK supports 2 pixel per clock, so pixel clock can be up to 2 * cdclk."

So, this reverts commit 97f55ca5b662 ("drm/i915/glk: limit pixel
 clock to 99% of cdclk workaround")

Fixes: 97f55ca5b662 ("drm/i915/glk: limit pixel clock to 99% of cdclk workaround")
