mainboard/lenovo/t410: Add new port

The port is based on the x201 / t410s.
2537-vg5 / i5, no discrete gpu

Tested and working:
* Native raminit
* Native gfxinit
* Booting Seabios 1.12.1
* Booting from EHCI
* Running GNU/Linux 5.0.0
* No errors in dmesg
* EHCI debug on the devices left side, bottom-right
* Keyboard
* Fn keys (Mute, Volume, Mic)
* Touchpad
* TPM
* Wifi
* Sound
* USB
* Ethernet
* S3 resume
* VBOOT

Testing in progress.

Untested:
* VGA
* Displayport
* Docking station

Bugs:
* AC adapter can't be read from ACPI
* TPM not working with VBOOT and C_ENV BB

Details for flashing externally:
1. Disconnect all power
2. Connect the external flasher
3. Connect the power cord (This fixes internal power control)
4. Remove the power cord
