tegra: video: use modedb to specify frame buffer resolution
Allow to specify framebuffer videomode using kernel command line
parameters. NVIDIAs binary X driver later on picks up those settings
and start X with current mode settings, if no EDID data are available.
Reused some of the implementation from Stefan's work for modedb
support[1] on Tegra20/30
