Add a basic .dts file for MediaTek Genio 520/720 EVKs. This will suffice
until an upstream devicetree is available from Linux.

These boards are virtually identical (other than some camera
capabilities) so share mostly the same devicetree.

Switch to OF_UPSTREAM to make use of the upstream device trees.

Remove the now obsolete device tree files:
- imx8mn-var-som-symphony.dts
- imx8mn-var-som.dtsi

Enable OF_UPSTREAM for i.MX8ULP EVK so that devicetree imported from
Linux kernel release can be used.

If mailbox@29220000 is enabled, gd->arch.ele_dev will be set to this
device for communication with ELE firmware. This is incorrect because
mu@27020000 is the MU used for communication with the ELE firmware. To
prevent misconfiguration, disable mailbox@29220000.

The driver model for watchdog timer is not enabled yet, so disable wdog3
temporarily.

This pull request brings together a set of fixes and enhancements across
the SoCFPGA platform family, with a focus on MMC/SPL robustness, EFI
boot enablement, and Agilex5 SD/eMMC support.

CI: https://source.denx.de/u-boot/custodians/u-boot-socfpga/-/pipelines/28776

Highlights:

  *
    SPL / MMC:
      o
        Fix Kconfig handling for
        SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION_TYPE
      o
        Correct raw sector calculations and respect explicit sector values
        when loading U-Boot from MMC in SPL
      o
        Adjust raw MMC loading logic for SoCFPGA platforms
  *
    EFI boot:
      o
        Permit EFI booting on SoCFPGA platforms
      o
        Disable mkeficapsule tool build for Arria 10 where unsupported
  *
    Agilex5:
      o
        Upgrade SDHCI controller from SD4HC to SD6HC
      o
        Enable MMC and Cadence SDHCI support in defconfig
      o
        Add dedicated eMMC device tree and defconfig for Agilex5 SoCDK
      o
        Revert incorrect GPIO configuration for SDIO_SEL
      o
        Refine U-Boot DT handling for SD and eMMC boot variants
  *
    SPI:
      o
        Allow disabling the DesignWare SPI driver in SPL via Kconfig
  *
    Board / configuration fixes:
      o
        Enable random MAC address generation for Cyclone V
      o
        Fix DE0-Nano-SoC boot configuration
      o
        Remove obsolete or conflicting options from multiple legacy
        SoCFPGA defconfigs

Add dedicated device tree support for eMMC configuration on the Agilex5
SoCDK board, providing an alternative to the default SD card setup.

Changes to socfpga_agilex5.dtsi:
-
- Configure always-on regulator for stable eMMC operation

New device tree files:
- socfpga_agilex5_socdk_emmc.dts: Main eMMC device tree configuration
  * Configure for eMMC operation (no-sd, no-sdio, non-removable)
  * Set 8-bit bus width and high speed capability
  * Add timing parameters for legacy and SDR modes
  * Configure voltage supplies for eMMC power and I/O
  * Add fixed 1.8V regulator for eMMC I/O voltage supply

- socfpga_agilex5_socdk_emmc-u-boot.dtsi: U-Boot specific additions
  * Include common Agilex5 U-Boot configurations
  * Set SPL boot order with eMMC support
  * Enable necessary peripherals for boot-time operation

Configuration files:
- configs/socfpga_agilex5_emmc_defconfig: eMMC-specific configuration
  * Inherit from base Agilex5 configuration
  * Disable GPIO regulator support (not needed for fixed eMMC setup)
  * Set eMMC-specific device tree

Build system integration:
- Add socfpga_agilex5_socdk_emmc.dtb target to Makefile
