Add support for UCM-iMX95 Evaluation Kit platform
The CompuLab UCM-iMX95 Evaluation Kit provides a platform for comprehensive evaluation of the NXP i.MX95 application processor. This change adds support in NixOS hardware to provide a template for customized i.MX95-based platforms. UCM-iMX95: https://www.compulab.com/products/som-evaluation-kits/ucm-imx95-evaluation-kit/ Signed-off-by: Govind Singh <[email protected]>
