soc/intel/alderlake: Allow channel 0 for DDR5 memory-down
This matches the change done for DDR4 in commit 8509c25eece8
("soc/intel/alderlake: Allow channel 0 for memory-down").
Fixes detection of the on-board RAM (Samsung M425R1GB4BB0-CQKOD) on the
System76 Lemur Pro 12 (Clevo L140AU). The Clevo L140*U are the only
boards in the tree using mixed memory topology.
