PATCH v2 1/2 arm64: tegra: Prepare for supporintg the Jetson Xavier NX with eMMC

There are two versions of the Jetson Xavier NX system-on-module; one with a micro SD-card slot and one with an eMMC. Currently, only the system-on-module with the micro SD-card slot is supported. Before adding support for the eMMC variant, move the common device-tree parts of the existing Jetson Xavier NX system-on-module board (p3668-0000) and reference carrier board (p3509-0000) into include files that can be used by both Jetson Xavier NX variants.

Ugh, looks like a typo in the $subject. Please let me know if I should resend.
