Andreas Reis a841c8da09 Radxa Zero 3: Switch to U-Boot v2025.10-rc2
Switch to newer U-Boot since it works reliably and provides upstream
improvements.

Add patch/u-boot/v2025.10 and the generic patch, as BOOTPATCHDIR cannot
be unset (fallback to legacy fails).

BOOT_SCENARIO="binman-atf-mainline" cannot be set here since it applies
globally to the CSC file and would break branch=vendor. Users who want
it can enable it manually.
