Revert "arm64: tegra: Add interconnect properties for Tegra210"

Commit 59a42707a094 ("arm64: tegra: Add interconnect properties for
Tegra210") populated interconnect properties for Tegra210 and this is
preventing the Tegra DRM driver from probing successfully. The following
error is observed on boot ...

 drm drm: failed to initialize 54240000.dc: -517

For now revert this change, until a fix is available.
