[PATCH 6/8] configs: add defconfigs for am6254atl

[Bryan Brattlof]

On October 22, 2025 thus sayeth Anshul Dalal:
> OP-TEE for current K3 devices resides from 0x9e800000 to 0xa0000000
> which needs to be moved to 0x80080000 to free up space at end of DDR in
> systems with 512MiB of memory. This is required to allow U-Boot to
> relocate to end of DDR before booting to the kernel.
> 
> Therefore defconfigs for AM6254atl include the respective existing AM62x
> configs with updated dt for r5 and modified memory map for a53 SPL to
> account for the new OP-TEE address.
> 
> Also make Bryan Brattlof and Tom Rini the maintainers for AM6254atl SIP.

I think this may have been leftover from some experimentation.
Do we still need the bloblist stuff?
