arm64: tegra: Add common nodes to AGX Orin module

The AGX Orin module boards contain common nodes that can
be moved to the included module dtsi. This eliminates
redundancy within the files and reduces lines of code.
Data from tegra234-p3701-0000 and tegra234-p3701-0008 that
is common is now in tegra234-p3701.dtsi.
