Convert gpio-davinci dt-binding documentation from txt to yaml format.

changes since v1:
- combined the individual compatible properties into one enum
- added maxItems and minItems properties for gpio-line-names and
interrupts
- updated the description of interrupts property
- removed the description for properties that are general
- updated the pattern property for gpio hog to indicate any sort
node name based on its usage
- corrected the example wakeup gpio node name

-Davinci/Keystone GPIO controller bindings
-
-Required Properties:
-- compatible: should be "ti,dm6441-gpio": for Davinci da850 SoCs
- "ti,keystone-gpio": for Keystone 2 66AK2H/K, 66AK2L,
- 66AK2E SoCs
- "ti,k2g-gpio", "ti,keystone-gpio": for 66AK2G
- "ti,am654-gpio", "ti,keystone-gpio": for TI K3 AM654
- "ti,j721e-gpio", "ti,keystone-gpio": for J721E SoCs
- "ti,am64-gpio", "ti,keystone-gpio": for AM64 SoCs
-
-- reg: Physical base address of the controller and the size of memory mapped
- registers.
-
-- gpio-controller : Marks the device node as a gpio controller.
-
-- #gpio-cells : Should be two.
- - first cell is the pin number
- - second cell is used to specify optional parameters (unused)
-
-- interrupts: Array of GPIO interrupt number. Only banked or unbanked IRQs are
- supported at a time.
-
-- ti,ngpio: The number of GPIO pins supported.
-
-- ti,davinci-gpio-unbanked: The number of GPIOs that have an individual interrupt
- line to processor.
-
-- clocks: Should contain the device's input clock, and should be defined as per
- the appropriate clock bindings consumer usage in,
-
- Documentation/devicetree/bindings/clock/keystone-gate.txt
- for 66AK2HK/66AK2L/66AK2E SoCs or,
-
- Documentation/devicetree/bindings/clock/ti,sci-clk.txt
- for 66AK2G SoCs
-
-- clock-names: Name should be "gpio";
-
-Currently clock-names and clocks are needed for all keystone 2 platforms
-Davinci platforms do not have DT clocks as of now.
-
-The GPIO controller also acts as an interrupt controller. It uses the default
-two cells specifier as described in Documentation/devicetree/bindings/
-interrupt-controller/interrupts.txt.
-
-Example:
-
-gpio: gpio@1e26000 {
- compatible = "ti,dm6441-gpio";
- gpio-controller;
- #gpio-cells = <2>;
- reg = <0x226000 0x1000>;
- interrupt-parent = <&intc>;
- interrupts = <42 IRQ_TYPE_EDGE_BOTH 43 IRQ_TYPE_EDGE_BOTH
- 44 IRQ_TYPE_EDGE_BOTH 45 IRQ_TYPE_EDGE_BOTH
- 46 IRQ_TYPE_EDGE_BOTH 47 IRQ_TYPE_EDGE_BOTH
- 48 IRQ_TYPE_EDGE_BOTH 49 IRQ_TYPE_EDGE_BOTH
- 50 IRQ_TYPE_EDGE_BOTH>;
- ti,ngpio = <144>;
- ti,davinci-gpio-unbanked = <0>;
- interrupt-controller;
- #interrupt-cells = <2>;
-};
-
-leds {
- compatible = "gpio-leds";
-
- led1 {
- label = "davinci:green:usr1";
- gpios = <&gpio 10 GPIO_ACTIVE_HIGH>;
- ...
- };
-
- led2 {
- label = "davinci:red:debug1";
- gpios = <&gpio 11 GPIO_ACTIVE_HIGH>;
- ...
- };
-};
-
-Example for 66AK2G:
-
-gpio0: gpio@2603000 {
- compatible = "ti,k2g-gpio", "ti,keystone-gpio";

Missed v2 - copy pasting here also:
I see that gpio-hog.yaml dtschema has been added.
Can it be reused here and how?
