Convert Amlogic Meson pin controller binding to yaml.

Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com>
---
v2:
- consider that more than one compatible can be set
- remove bus part from example
v3:
- remove minItem/maxItem properties for compatible
v4:
- split patch to be able to deal with the different reg/reg-names

No, this cannot be true.

This goes to the same place as in example-schema, so before required.

Missing required-compatible.

I don't think this readable. Properties should rather reference the
schema, and now you allow evaluation of anything. Which probably caused
your wrong additionalProperties in the first place.

This could be part of node definition below.

Same problems... and further as well.

- - reg: address and size of registers controlling irq functionality
-
-=== GPIO sub-nodes ===
-
-The GPIO bank for the controller is represented as a sub-node and it acts as a
-GPIO controller.
-
-Required properties for sub-nodes are:
- - reg: should contain a list of address and size, one tuple for each entry
-   in reg-names.
- - reg-names: an array of strings describing the "reg" entries.
-   Must contain "mux" and "gpio".
-   May contain "pull", "pull-enable" and "ds" when appropriate.
- - gpio-controller: identifies the node as a gpio controller
- - #gpio-cells: must be 2
-
-=== Other sub-nodes ===
-
-Child nodes without the "gpio-controller" represent some desired
-configuration for a pin or a group. Those nodes can be pinmux nodes or
-configuration nodes.
-
-Required properties for pinmux nodes are:
- - groups: a list of pinmux groups. The list of all available groups
-   depends on the SoC and can be found in driver sources.
- - function: the name of a function to activate for the specified set
-   of groups. The list of all available functions depends on the SoC
-   and can be found in driver sources.
-
-Required properties for configuration nodes:
- - pins: a list of pin names
-
-Configuration nodes support the following generic properties, as
-described in file pinctrl-bindings.txt:
- - "bias-disable"
- - "bias-pull-up"
- - "bias-pull-down"
- - "output-enable"
- - "output-disable"
- - "output-low"
- - "output-high"
-
-Optional properties :
- - drive-strength-microamp: Drive strength for the specified pins in uA.
-			    This property is only valid for G12A and newer.
-
-=== Example ===
