leds: pca963x: Add bindings to invert polarity
Add a new DT property, nxp,inverted-out, to invert the polarity of the output. Tested on PCA9634. Signed-off-by: Anders Darander <anders@chargestorm.se> Acked-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Jacek Anaszewski <jacek.anaszewski@gmail.com>

- nxp,period-scale : 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,inverted-out: invert the polarity of the generated PWM
Each led is represented as a sub-node of the nxp,pca963x device.
