dt-bindings: leds: nxp,pca963x: Add multicolor LED support

Browse Source 
Add support for grouping individual PCA963x channels into a multicolor
LED by introducing a multi-led@N node pattern. This follows the
convention established by other multicolor LED drivers such as
kinetic,ktd202x.

This is necessary to support and model hardware setups where multiple
PWM channels drive a single physical RGB LED.
