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.
