Subject: [PATCH v4] dt-bindings: gpio: lsi,zevio-gpio: convert to dtschema

Convert Zevio GPIO Controller from text to dtschema.
Adding `interrupts` property fixes the following warning:
linux/out/arch/arm/boot/dts/nspire/nspire-tp.dtb: gpio@...00000:
'interrupts' does not match any of the regexes: 'pinctrl-[0-9]+'`
while executing `make dtbs_check` on Texas Instruments
nspire boards.

Signed-off-by: Pratik Farkase <pratik.farkase@...sweden.com>
---
Changes in v4:
- Updated commit message to describe addition of `interrupt`
property
Changes in v3:
- Updated relative path filename to match actual path filename
- Added `interrupts` property
Changes in v2:
- Renamed file from `gpio-zevio.yaml` to `lsi,zevio-gpio.yaml`
- Fixed the space indentation in example

-Zevio GPIO controller
-
-Required properties:
-- compatible: Should be "lsi,zevio-gpio"
-- reg: Address and length of the register set for the device
-- #gpio-cells: Should be two. The first cell is the pin number and the
-  second cell is used to specify optional parameters (currently unused).
-- gpio-controller: Marks the device node as a GPIO controller.
-
-Example:
-	gpio: gpio@...00000 {
-		compatible = "lsi,zevio-gpio";
-		reg = <0x90000000 0x1000>;
-		gpio-controller;
-		#gpio-cells = <2>;
