The normal method is just to cat the two files together, like so:
 $ cat zImage <filename>.dtb > zImage_w_dtb

See https://community.freescale.com/thread/315543 for one example, on ARM.
I'm not sure what the status is for appended DTBs on powerpc, but it's
easy enough you can just try it and see what happens.
