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 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.

You must remove the following parts to access the SPI flash chip:
![x230s_bc_removed](x230s_bc_removed.jpg)
* Base cover
The [Hardware Maintenance Manual](https://download.lenovo.com/ibmdl/pub/pc/pccbbs/
mobiles_pdf/x230s_hmm_en_0c10860_01.pdf) could be used as a guidance of disassembly.
The SPI flash chip (W25Q128.V in the form of SOIC-8 for the author's X230s, but varying is possible)
is located at the circled place.
Unlike [most Ivy Bridge ThinkPads](Ivy_Bridge_series.md), X230s has a single 16MiB SPI flash chip.
The general [flashing tutorial](../../flash_tutorial/index.md) has more details.
