Convert the Texas Instruments PCM186x audio ADC bindings to DT schema.
---
Changes in v4:
- Corrected subject dt_bindings:sound to Asoc: dt_bindings:
- Corrected the filename to match one of the compitables in the file 
- ti,pcm186x.yaml to ti,pcm1862.yaml
- Link to v3: https://lore.kernel.org/r/20251029-dtbs-v3-1-3cc162221c22@gmail.com

Changes in v3:
- Unicode FEFF character was present in the begining of the file,
- Removed unicode character.
- Link to v2: https://lore.kernel.org/r/20251026-dtbs-v2-1-cd3b713a288e@gmail.com

Changes in v2:
- Fixes as per the reviews suggested for the v1.

-Texas Instruments PCM186x Universal Audio ADC
-
-These devices support both I2C and SPI (configured with pin strapping
-on the board).
-
-Required properties:
-
- - compatible : "ti,pcm1862",
-                "ti,pcm1863",
-                "ti,pcm1864",
-                "ti,pcm1865"
-
- - reg : The I2C address of the device for I2C, the chip select
-         number for SPI.
-
- - avdd-supply: Analog core power supply (3.3v)
- - dvdd-supply: Digital core power supply
- - iovdd-supply: Digital IO power supply
-        See regulator/regulator.txt for more information
-
-CODEC input pins:
- * VINL1
- * VINR1
- * VINL2
- * VINR2
- * VINL3
- * VINR3
- * VINL4
- * VINR4
-
-The pins can be used in referring sound node's audio-routing property.
-
-Example:
-
-	pcm186x: audio-codec@4a {
-		compatible = "ti,pcm1865";
-		reg = <0x4a>;
-
-		avdd-supply = <&reg_3v3_analog>;

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/sound/ti,pcm1862.yaml: $id: Cannot determine base path from $id, relative path/filename doesn't match actual path or filename
 	 $id: http://devicetree.org/schemas/sound/ti,pcm186x.yaml
 	file: /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/sound/ti,pcm1862.yaml

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20251030-dtbs-v4-1-3fff32221119@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
