Subject: [PATCH v2 0/3] arm64: dts: Add support for Ultratronik i.MX8MP Ultra-MACH SBC

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..

Changes in v2:
  - Use `enum` with `const:` values in fsl.yaml to correctly represent multiple compatibles.
  - Updated SPI child node name to use the generic `nfc-transceiver` per DT naming conventions.
  - Renamed several peripheral nodes (`crypto@35`, `pmic@25`, etc.) to standard names.
  - Minor formatting cleanup and compliance fixes per review feedback.

Tested on hardware with:
  - Serial console
  - HDMI output via LCDIF pipeline
  - eMMC and SD boot
  - USB gadget and host modes
  - Ethernet and basic SPI/I2C devices

Feedback is welcome.
