kernel-yocto: restore missing configuration meta data

kernel-yocto: restore missing configuration meta data

Some of the meta-data from the 4.4 kernel was missing from the 4.8
branch. This resulted in some functionality drops and also a size/time
increase in the kernel build (due to debug being turned on).

With this resync, we now have the missing config restored.
