xserver xfree86/modes: Update Default Mode Selection in xf86Crtc to fix issue #122

This change makes the Default Mode Selection set itself to Highest Refresh Rate at and after 75hz or fallback to the default setting in xorg.conf as requested by issue https://github.com/X11Libre/xserver/issues/122

Feel free to simplify or edit the function for further compatibility.

Rebased from https://github.com/X11Libre/xserver/pull/263

@HaplessIdiot These modes are probed from the monitor or the graphics card?

these are probed from the EDID firmware in the monitor. it loads default modes from there and then i run this check to decide which one to use.
