There is more than one version of the I-pipe patch for 3.14.44,
actually there are 7. Which one of the 7 are you using?
You can find the history of I-pipe patches for 3.14.44 here:
https://xenomai.org//downloads/ipipe/v3.x/arm/older/
The files,
which will be changed in the patch for kernel 3.14.44 have just little
differences.
My point is: the I-pipe patch, provided that you are using
the last version, patches some device tree files, but these may not
be the device tree files you use with your kernel fork.
To be completely specific I am referring to the following hunk:
diff --git a/arch/arm/boot/dts/imx6qdl.dtsi
b/arch/arm/boot/dts/imx6qdl.dtsi
index fb28b2e..bf84723 100644

Does the device tree file you use include this file?

I used the ipipe-core-3.14.44-arm-16.patch.
The hunk that you reffering to was defined as followed:
