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.

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.

Convert the Texas Instruments TPS65217 bindings to DT schema.
During the conversion, the following updates were made:
- Documented the 'regulators', 'charger' and 'pwrbutton' child nodes,
which are used by the boards but were missing from the old txt
binding.
- Documented the 'interrupts', 'interrupt-controller', '#interrupt-cells'
and 'ti,pmic-shutdown-controller' properties, which are used by the
am335x boards and read by the driver.
The regulator/tps65217.txt binding documented the same 'ti,tps65217'
compatible and is superseded by this schema, so remove it as well.

The "gpio" trigger is used to control LEDs by the level of a GPIO input
referenced by the trigger-sources property. This is already documented
in the trigger-sources property description and is used in at least one
devicetree (am335x-regor.dtsi). Document it so validation of those and

There is no use of double colon '::' in YAML. OTOH, the literal style
block, e.g. using '|' treats all characters as content [1] therefore
single use of ':' in descriptions is perfectly fine, whenever '|' is
used.
Cleanup existing code, so the confusing style won't be re-used in new
contributions.

In some cases, for example when using multiple instances of
leds-group-multicolor, a board may have multiple multi-leds which can't
be distinguished by unit address. In such cases it should be possible to
name them differently, for example multi-led-0 and multi-led-1. This
patch adds another node name pattern to leds-class-multicolor.yaml to
allow such names.
