ARM SoC fixes for v5.12, part 4

These should be the final fixes for v5.12. There is one fix for SD card
detection on one Allwinner board, and a few fixes for the Tegra
platform that I had already queued up for v5.13 due to a communication
problem. This addresses MMC device ordering on multiple machines,
audio support on Jetson AGX Xavier and suspend/resume on Jetson TX2.
