From: Michael Srba <michael.srba@seznam.cz>
Attempting to enable these devices causes a "synchronous external abort". Suspected cause is that the debug power domain is not enabled by default on this device. Disable these devices for now to avoid the crash.
See: https://lore.kernel.org/linux-arm-msm/20190618202623.GA53651@gerhold.net/
