soc/tegra: Use ARM SMCCC to get chip ID, revision, and platform info

Browse source

Tegra410 and Tegra241 deprecate the HIDREV register. The recommended
method is to use ARM SMCCC to retrieve the chip ID, major and minor
revisions, and platform information.

Prefer ARM SMCCC when the platform supports it; fall back to HIDREV
otherwise. Behavior on older Tegra SoCs that do not support ARM SMCCC
remains unchanged.
