soc/tegra: Changes for v5.19-rc1

This set of changes adds nvmem cell lookup entries for Tegra194 that are
used to read calibration data from the SoC fuses, and updates the reset
sources for Tegra234.

Other than that, included is a minor build fix for a missing dependency
that can be encountered very rarely in random config builds. Lastly some
kerneldoc comments are added to avoid build warnings.
