USE_CIP_KERNEL_CONFIG may not be defined in all layers using the
isar-cip-core layer, so we end up with the following warnings:

${MACHINE}_defconfig needs to be added to SRC_URI only if
USE_CIP_KERNEL_CONFIG is set to "1".

There is one in-tree machine definition (the bbb) that does not set
USE_CIP_KERNEL_CONFIG to "1" but still needs the defconfig added.
A machine specific SRC_URI was set to take care of that.

Closes #7.

The easier way would have been to delete file://${KERNEL_DEFCONFIG}
instead of create the logic anew. The conditional function should allow
an empty string.

I'm not yet sure which string should be empty and would break with the
new version. Can you elaborate?
