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)
