This evening I've been reading some upstream patches, looking through Yocto BSPs for similar platforms, and also referencing the Android kernel and I've come to a simlar realization that a lot has changed with the host and device controller drivers. Developers have put in a lot of work to improve CherryTrail and BayTrail support throughout the kernel. I'll try a 4.18 kernel on my board and report the results. Thanks again for the suggestion!
