xfree86: fix gtf support detection for EDID 1.4
According to the "VESA Enhanced EDID Standard", all GTF compliant
displays are continuous frequency.
The GTF support flags in 'Display Range Limits Descriptor' cannot be
used if the display is a non-continuous frequency multi-mode display.
Closes #1105
