    xfree86: fbdevhw: fix pci detection on recent Linux
    
    Linux kernel v6.9 has changed the symlink to point to the parent device. This
    breaks fbdev_open() detection logic. Change it to use the subsystem symlink
    instead which will remain stable.
    
    Kernel v6.8:
    
    [    14.067] (II) fbdev_open() sysfs_path=/sys/class/graphics/fb0
    [    14.067] (II) fbdev_open() buf=../../devices/platform/vesa-framebuffer.0/graphics/fb0
    
    Kernel v6.9:
    
    [    15.609] (II) fbdev_open() sysfs_path=/sys/class/graphics/fb0
    [    15.609] (II) fbdev_open() buf=../../devices/pci0000:00/0000:00:01.0/vesa-framebuffer.0/graphics/fb0
