cbvga: reuse svga modes definitions from svgamodes.c

For cbvga only modes with MM_DIRECT are usable, so skip the other ones.
This effectively adds the following modes:

    { 0x10D, { MM_DIRECT, 320,  200,  15, 8, 16, SEG_GRAPH } },
    { 0x10E, { MM_DIRECT, 320,  200,  16, 8, 16, SEG_GRAPH } },
    { 0x10F, { MM_DIRECT, 320,  200,  24, 8, 16, SEG_GRAPH } },
    { 0x140, { MM_DIRECT, 320,  200,  32, 8, 16, SEG_GRAPH } },
