The allOf conditional grouped both chips under a single else branch capping reg at a maximum of 7. Give pca9634 its own if/then block and set maximum: 15 unconditionally in the top-level led@ node, making it the default for pca9635 and any future compatible. Also tighten the node name regex from [0-9a-f]+ to [0-9a-f] to match the single-digit hardware limit.
