lenovo/s230u: Add Thinkpad Twist (S230U)

Created using autoport plus some manual work and copying from G505S to
account for the non-H8 EC.

This model uses the same ENE KB9012 EC as the G505S.

Tested:
- Mainboard variant with 8GB Elpida DDR3
- SeaBIOS payload
- Booting into Linux 4.9.6 with Debian/unstable installed on the
  internal HDD/SDD slot
- Native raminit
- Both native VGA init and option rom VGA init
- Basic TPM functionality (auto-detection and RNG)
- Battery status readout
- Basic ACPI functions (power button event; power-off; reboot)
- thinkpad-acpi hotkey functions
- thinkpad-acpi LED control (red thinkpad LED)
- Suspend to RAM and resume works
- Mini displayport output works

Known issues:
- Patches needed for EC battery support
  https://review.coreboot.org/#/c/18348/
  https://review.coreboot.org/#/c/18349/
- No thermal zone since temperature sensing is not H8-compatible
  and needs to be reverse engineered.

Not tested:
- msata/wwan (probably works)
