kernel/yocto: ensure that defconfigs are processed first

It is uncommon that a BSP definition and a defconfig are used in
a single configuration. That being said, it is a valid way to
organize kernel configuration meta data.

When a defconfig is used, either on the src_uri or from in
the kernel tree, it is normally expected that it is the baseline,
with all options applied on top of it.

With this commit, we detect either type of defconfig and ensure
that it is used first, followed by the fragments in their
previous order. This allows existing configuration stacks to
remain the same, while ensuring that a defconfig combined stack
works as expected.
