arm64: tegra: Add Lenovo ThinkEdge SE70 device tree

Browse Source 
Add initial device tree support for the Lenovo ThinkEdge SE70, an
industrial edge gateway based on the NVIDIA Jetson Xavier NX module
(P3668-0001) with a custom carrier board.

This initial submission includes:
- 40-pin expansion header pinmux configuration
- External Micro SD card slot with dedicated 3.3V regulator
- I2C bus for 40-pin header

Static verification passed: dt_binding_check and dtbs compilation
complete without errors.
