This patch series adds support for the Ultratronik i.MX8MP-based Ultra-MACH SBC.

The Ultra-MACH SBC is an industrial-grade single-board computer based on the NXP i.MX8M Plus SoC. This initial support includes:

- Updating the MAINTAINERS file to include the new board in the Ultratronik support section.
- Adding a compatible string entry for the board to `fsl.yaml` in device tree bindings.
- Introducing a new device tree source file `imx8mp-ultra-mach-sbc.dts` with basic hardware support.

This series is modeled after the support added for the STM32MP157C-based Ultra-FLY SBC and aims to follow the conventions used for other i.MX8MP boards in mainline.

Tested on hardware with:
- Serial console
- HDMI output via LCDIF pipeline
- eMMC/SD-card boot

Feedback is welcome.
