[PATCH v2 5/5] fbdev: tdfxfb: Program the initial video mode

[Daniel Palmer]

If the card does not get bound to by fbcon set_par() never happens
and the initial video mode is not setup and the display detects
no signal.

Program the video mode and also clear the framebuffer memory so
random garbage isn't displayed.
