From: Marek Vasut <marek.vasut@mailbox.org>

The OE 5.0 implementation of fitImage generation did not include the
kernel property in DTBO configuration node subnodes, while the current
OE 6.0 implementation does. The previous implementation was correct,
because kernel together with only a DTBO overlay can not form bootable
result. The kernel property should only be part of the configuration
subnode which includes both kernel and DTB. Fix this.
