configs: socfpga_agilex5: Enable MMC and Cadence SDHCI support

Browse Source 
Enable MMC support with Cadence SDHCI controller for both SPL and
U-Boot proper on Agilex5 platform to support SD card operations in
legacy and high speed timing modes.

MMC controller configuration:
- Enable MMC subsystem (CONFIG_MMC=y, CONFIG_DM_MMC=y)
- Add Cadence SDHCI controller support (CONFIG_MMC_SDHCI_CADENCE=y)
- Enable SDHCI with ADMA support for better performance
- Add MMC command support for user interaction

SPL configuration:
- Enable MMC support in SPL (CONFIG_SPL_DM_MMC=y)
- Add SDHCI ADMA support in SPL (CONFIG_SPL_MMC_SDHCI_ADMA=y)
- Enable GPIO support in SPL (CONFIG_SPL_DWAPB_GPIO=y)

Voltage regulator support:
- Add device model regulator framework (CONFIG_DM_REGULATOR=y)
- Enable fixed voltage regulator support for card power
- Add GPIO-controlled regulator for I/O voltage switching
- Include regulator support in SPL for early initialization

These changes enable SD card functionality with legacy and high speed
timing modes, providing proper voltage regulation and GPIO control
for the Agilex5 SoCDK platform.
