drm: Add DRM_MODE_TV_MODE_MONOCHROME
Add this as a value for enum_drm_connector_tv_mode, represented
by the string "Mono", to generate video with no colour encoding
or bursts. Define it to have no pedestal (since only NTSC-M calls
for a pedestal).
Change default mode creation to acommodate the new tv_mode value
which comprises both 525-line and 625-line formats.
