this breaks non linux-yocto kernels which are using the kernel infra
from OE-Core
since they may not have kmeta structure and bsp_definition may be empty for them
so either provide a way to override bsp_definition to something dummy or infact
fall back to dummy by default with a warning or note during parse
time. fatal is a bit harsh here.
