    mainboard: add support for lenovo x1 carbon gen 1
    
    copy-paste from x230 and add hardcoded spd for elpida.
    usb debug works on the front left usb port.
    
    open ToDos:
    - remove unsued sata ports
    - use autoport to see if it generates differences to x230
    - SPD based on inteltool with elpida 4GB. need to find uefi spd.bins
    - power led doesn't pulse (write in acpi to the ec that it should pulse
    the LED)
    - test msata port if soldered
    - use pins to select the right spd (4 vendors x 2 size)
    - check if buttons doesn't work because of wrong acpi (middle mouse and
    rihgt mouse click of trackpad buttons doesnt work)
    - native graphics init works but is somehow broken before linux (because of dts value?)
    - check why device consumes more power (+ 3W while idle)
     - check if thermal/power/freq MSR are different
     - check if it's display backlight
     - check how big is the consumtion when turning display off
    - enable pci/sata link power safe
    
    Thanks to Holger Levsen for the device.
