soc/tegra: Clean-up fuse-helper

Browse Source 
The option CONFIG_TEGRA_FUSE_UPSTREAM is not needed any longer because
we always want to enable this for Linux v5.15. Therefore, remove this
option completely.

The function tegra_fuse_control_read() is not used anywhere and so we
can also remove this too.
