[Intel-gfx] [PATCH xf86-video-intel] sna/uxa: add drm modes for no-GTF pannels

EDID1.4 replaced GTF Bit with Continuous or Non-Continuous Frequency
Display.

SNA still check this bit as GTF support, only defined modes in EDID
will be set.

Correct the GTF support check, then add more modes.

Note, gtf_supported must be included in xserver.
