Hello Alexander Couzens, Patrick Rudolph, build bot (Jenkins),
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/37115
to look at the new patch set (#3).

[WIP] sb/intel/bd82x6x: Support ME Software Disable Mode
AFAIK, ME is supposed to enter Software Temp Disable Mode on the next reboot after receiving the disable command.
But my tests on X230 (ME firmware 8.1.1416.40) show that CF9 reset doesn't help here and user must manually perform power off/power on cycle.
So for now working algorithm to disable ME is as follows: - run `nvramtool -w me_disable=Enable` - reboot - power off - power on - run `intelmetool -m` to verify that ME is in soft temp disable mode.
To enable ME: - run `nvramtool -m me_disable=Disable` - reboot
TODO: if it's possible, find a way to perform correct program reset so that user wouldn't have to do one more power off/power on.
