    offb: Fix setting of the pseudo-palette for >8bpp · 1bb0b7d2
    Benjamin Herrenschmidt authored
    When using a >8bpp framebuffer, offb advertises truecolor, not directcolor,
    and doesn't touch the color map even if it has a corresponding access method
    for the real hardware.
    
    Thus it needs to set the pseudo-palette with all 3 components of the color,
    like other truecolor framebuffers, not with copies of the color index like
    a directcolor framebuffer would do.
    
    This went unnoticed for a long time because it's pretty hard to get offb
    to kick in with anything but 8bpp (old BootX under MacOS will do that and
    qemu does it).
