Have you tried this kernel? I don't remember if it has imx6UL support, but at least it's a closer base kernel with imx6 support. I don't think linux-yocto-rt_4.1 has imx6UL support also, as imx6UL was not around on jethro. imx6ulevk machine file was introduced only 2016. Maybe it's easier to use a more current yocto release instead.
