dt-bindings: leds: nxp,pca963x: fix reg maximum for pca9635

This commit updates the pca963x binding to support 16 LED channels on the
pca9635. It gives pca9634 its own conditional block and sets the maximum
registry value to 15 unconditionally in the top-level node.

[Severity: Medium]
The commit message states the node name regex was tightened from
^led@[0-9a-f]+$ to ^led@[0-9a-f]$, but it seems this was only applied to the
top-level patternProperties.

Does this conditional block in Documentation/devicetree/bindings/leds/nxp,pca963x.yaml
also need to be updated to match the top-level regex?

Leaving it as ^led@[0-9a-f]+$ creates a mismatch, and there may be other
allOf conditional blocks (like the one for pca9632/pca9633) that were also
missed.
