dt-bindings: leds: pca963x: Convert text bindings to YAML

Convert the pca963x DT bindings to YAML schema. The existing properties
are kept without modification, but the example is adapted to the latest
common bindings for LEDs.

+title: NXP PCA963x LED controllers
+

+  - Laurent Pinchart <[email protected]>
+
+description: |
+  The NXP PCA963x are I2C-controlled LED drivers optimized for
+  Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED is
+  individually controllable and has its own PWM controller.
+
+  Datasheets are available at

+  nxp,hw-blink:

+    description:
+      Use hardware blinking instead of software blinking

+      Invert the polarity of the generated PWM.
+
+  nxp,period-scale:
+    $ref: /schemas/types.yaml#/definitions/uint32
+    description:
+      In some configurations, the chip blinks faster than expected. This
+      parameter provides a scaling ratio (fixed point, decimal divided by 1000)
+      to compensate, e.g. 1300=1.3x and 750=0.75x.
+
+  nxp,totem-pole:
+    type: boolean
+    description:
+      Use totem pole (push-pull) instead of open-drain (pca9632 defaults to
+      open-drain, newer chips to totem pole).
