soc/tegra: fuse: Use platform info with SoC revision
Tegra pre-silicon platforms do not have chip revisions. This makes the
revision SoC attribute meaningless on these platforms.
Instead, populate the revision SoC attribute with a combination of the
platform name and the chip revision for silicon platforms, and simply
with the platform name on pre-silicon platforms.
