Since U-Boot 2025.07 pure SD Card

After testing, the major root case is
get_managers_addr. And this patch fix the
SD boot stall via pulling from offical.

This is intended for internal use and should be removed.

The condition for non-Agilex5 platforms should be rewritten because |sys-mgr| has already moved to the driver model for these platforms.

Similarly, the section for Agilex and Agilex7M using |clkmgr| can be removed, as both now use the driver model.


        else if (IS_ENABLED(CONFIG_TARGET_SOCFPGA_N5X))


The N5X section should be updated as:  "if (IS_ENABLED(CONFIG_TARGET_SOCFPGA_N5X))"

The remaining part of the function can remain intact.

We’ve already tested the above changes and they work as expected.


Thanks.
