Christian Schrötter cf541343a9 ec/lenovo/h8: Implement LOGO LED
Implement the red i-dot LED in the ThinkPad logo at the display lid.
On warm reboot the LOGO LED isn't automatically turned on by the EC.
Turn it on in the ramstage code, which allows to see when the reboot
has happened. (Similar to PWR LED; see change ID 88998)

Further testing on other devices running H8 EC is required!

TEST=LOGO LED is on after warm reboot on Lenovo T440p.
