note: nvpmodel.service is failing on 8GB variants of this board since it has 2 less cores than the 16GB variant (supported already) and since the nvpmodel configuration file was being recycled for all Orin NX variants. So, `nvpmodel.service` would try to change settings for 8 CPUs when only 6 exist. cf. https://docs.nvidia.com/jetson/archives/r35.3.1/DeveloperGuide/index.html for the mapping between Orin NX variant and Nvidia "P-number".

Description of changes
Add a
hardware.jetpack-nixos.skumodule option that allows for specifying the SKU (in addition to the already-available SOM). If set to indicate that the board is the 8 GB variant of an Orin NX then we use a compatiblenvpmodelconfiguration file.Testing
We used
systemctl edit --runtimeto add a block likeand
systemctl restart nvpmodeland saw the service was working. We also executed this same command from the command line. We haven't tested all power modes since we only want to fix the service, right now, and the service's default power mode (0) is exactly what we want. We lost access to the hardware before we could run tests on the other modes. If this change set is accepted then we can test other modes and submit an issue if we find they're not working.
