[PATCH v5 1/4] dt-bindings: leds: nxp,pca963x: fix reg maximum for pca9635

The pca9635 supports 16 LED channels, unlike the pca9634 which only
supports 8. 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.
