Pull request: SoCFPGA changes for u-boot-socfpga-next-20250930

[Chee, Tien Fong]

Dear Tom,

SoCFPGA updates for v2025.10

This pull request brings a set of updates across SoCFPGA platforms
covering Agilex5, Agilex7, N5X, and Stratix10. The changes include:

* Agilex5 enhancements:
  - USB3.1 enablement and DWC3 host driver support
  - System Manager register configuration for USB3
  - Watchdog timeout increase and SDMMC clock API integration
  - dcache handling improvements in SMC mailbox path
  - Enable SPL_SYS_DCACHE_OFF in defconfig

* Clock driver improvements:
  - Introduce dt-bindings header for Agilex clocks
  - Add enable/disable API and EMAC clock selection fixes
  - Replace manual shifts with FIELD_GET usage

* DDR updates:
  - IOSSM mailbox compatibility check
  - Correct DDR calibration status handling

* Device tree changes:
  - Agilex5: disable cache allocation for reads
  - Stratix10: add NAND IP node
  - Enable driver model watchdog
  - Enable USB3.1 node for Agilex5

* Config cleanups:
  - Simplify Agilex7 VAB defconfig
  - Remove obsolete SYS_BOOTM_LEN from N5X VAB config
  - Enable CRC32 support for SoCFPGA
  - Increase USB hub debounce timeout

Overall this set improves reliability of DDR and cache flows,
adds missing USB and MMC features for Agilex5, and refines clock
and configuration handling across platforms.

This patch set has been tested on Agilex 5 devkit, and Agilex devkit.

Thanks.



Best regards,
