Subject: [PATCH 3/5] arm64: tegra: Drop unneeded status=okay on Tegra234

Device nodes are enabled by default and this DTSI file does not include
anything else, thus it is impossible that nodes were disabled before and
need to be re-enabled.  Adding redundant status=okay is just confusing
and suggests some other code flow.  Verified with dtx_diff.
