apalis/colibri_t30: fix HDMI hang issue
Initialisation of the framebuffer console on DVI-D aka HDMI always failed on monitors which report the vertical front porch to be 1 in their EDID. The fix now changes also the modedb and not only the list of videomodes with a compatible timing. This was particularly bad on Apalis T30 where this is activated by default. On Colibri T30 this was observed when enabling it using the fbcon=map:1 boot argument.
