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

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 PCIe
    - No docking
    - No TPM

Tested:
    - CPU i5-3337U
    - 8GiB SO-DIMM
    - Camera
    - PCIe 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 PCIe
    - USB3 ports
    - libgfxinit-based graphics 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.
