Merge tag 'u-boot-socfpga-next-20251217' of https://source.denx.de/u-boot/custodians/u-boot-socfpga into next

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
