libgfxinit: Add options to limit framebuffer size
Add maximum width and height options and set the default to 2560x1600 (WQXGA). The framebuffer will be scaled up to the displays' native resolutions. So this should help with tiny fonts on high-DPI displays. For laptops, reasonable defaults can be set at the mainboard level.
