Resume is failing because the ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT driver is attempting to power on a power-domain that is provided by the BPMP. While a proper fix for the resume sequencing problem is identified, disable the ACONNECT for Jetson TX2 temporarily to avoid breaking system suspend. Please note that ACONNECT driver is used by the Audio Processing Engine (APE) on Tegra, but because there is no mainline support for APE on Jetson TX2 currently, disabling the ACONNECT does not disable any useful feature at the moment.
