    drivers/video: drop framebuffer size constraints
    
    The limit 1900x1200 do not match real world devices (1900 looks like a
    typo, should be 1920). But in practice the limits are arbitrary and do
    not serve any real purpose. As discussed in "Increase framebuffer size
    to todays standards" thread, drop them completely.
    
    This fixes graphic console on device with 3840x2160 native resolution.

    drivers/video: drop unused limits
    
    MAX_BPP, MAX_FONT_W, MAX_FONT_H are not used in the code at all.
