[PATCH 17/54] dt-bindings: input: Convert Pixcir Touchscreen binding to a schema

The Pixcir Touchscreen Controller is supported by Linux thanks to
its device tree binding.

Now that we have the DT validation in place, let's convert the device
tree bindings for that driver over to a YAML schema.

-* Pixcir I2C touchscreen controllers
-
-Required properties:
-- compatible: must be "pixcir,pixcir_ts" or "pixcir,pixcir_tangoc"
-- reg: I2C address of the chip
-- interrupts: interrupt to which the chip is connected
-- attb-gpio: GPIO connected to the ATTB line of the chip
-- touchscreen-size-x: horizontal resolution of touchscreen (in pixels)
-- touchscreen-size-y: vertical resolution of touchscreen (in pixels)
-
-Optional properties:
-- reset-gpios: GPIO connected to the RESET line of the chip
-- enable-gpios: GPIO connected to the ENABLE line of the chip
-- wake-gpios: GPIO connected to the WAKE line of the chip

-Example:
-
- i2c@00000000 {
- /* ... */
-
- pixcir_ts@5c {
- compatible = "pixcir,pixcir_ts";
