mainboard/lenovo/x230: Add ThinkPad x230s as a variant

Browse Source 
The code is based on autoport and that for X230. Major differences are:
    - Only one DDR3 slot
    - HM77 PCH
    - M.2 socket instead of mini pci-e
    - no docking
    - no tpm

Tested:
    - CPU i5-3337U
    - Slotted DIMM 8GiB
    - Camera
    - pci-e and usb2 on M.2 slot with A key for wlan
    - sata and usb2  (no superspeed components) on M.2 slot with B key for wwan
    - On board SDHCI connected to pci-e
    - USB3 ports
    - libgfxinit-based graphic init
    - NVRAM options for North and South bridges
    - Sound
    - Thinkpad EC
    - S3
    - Linux 4.9 within Debian GNU/Linux stable, loaded from
      Seabios.

Untested:
    - Touch screen, which is said to work under ubuntu but not debian.
