soc/tegra: Changes for v6.2-rc1

In addition to a number of improvements and cleanups this contains a
fix for the FUSE access on newer chips, adds Tegra234 I/O pad support
and fixes various issues with wake events.

The SoC sysfs revision attribute is updated to include the platform
information so drivers can check for silicon vs. pre-silicon, among
other things.
