[Keith Hui (Code Review)]

Hello Angel Pons, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/81889?usp=email

to look at the new patch set (#2).

Change subject: sb/intel/ibexpeak: Sever bd82x6x source dependency

sb/intel/ibexpeak: Sever bd82x6x source dependency

It shares southbridge devicetree definition with bd82x6x, causing
changes made there to break builds for boards with this PCH. Give
ibexpeak its own copy.

TEST=abuild tested with lenovo/t410, lenovo/x201, packardbell/ms2290. Timeless binary did not change for all.
