usb: dt-bindings: ti,twlxxxx-usb: convert to DT schema

Hello,

This series converts the legacy TXT bindings for the TI TWL4030 and TWL6030 USB modules to the modern YAML DT schema format.

Thank you,
Jihed

Changes in v7:
- Patch (1/2) removed the corresponding twl4030 section from the old .txt binding file. Patch (2/2) which deletes the remaining twl6030 section; removes the file.

Changes in v6:
- Reworked 'interrupts' property in both patches to use a list of items with descriptions, per reviewer feedback.

Changes in v5:
- Split combined twlxxxx-usb binding into two dedicated files for TWL4030 and TWL6030 per maintainer feedback.
- Used more accurate header file for interrupt macros.
- Improved formatting in the examples.
- Patch 2/2 removes the old .txt file.

Changes in v4:
- This patch is split from larger series per maintainer feedback.
- v3 link:

    https://lore.kernel.org/all/[email protected]/

- Removed i2c node as it wasn't required by the old binding file.
- Updated node names to 'usb' and 'usb-phy' in the examples to follow generic naming conventions per the Device Tree specification.
- Replaced raw interrupt values with standard defines for clarity.
- Improved formatting in the examples for clarity and consistency.

Changes in v3:
- No changes.

Changes in v2:
- Added '#phy-cells' property to support PHY framework integration.

Convert the legacy TXT binding for the TWL4030 USB module to the modern YAML DT schema format. This adds formal validation and improves documentation using a conditional schema.

Remove the twl4030 section from the obsolete .txt binding file

Convert the legacy TXT binding for the TWL6030 USB module to the modern YAML DT schema format. This adds formal validation and improves documentation using a conditional schema.

The legacy twlxxxx-usb.txt file is no longer needed and is removed.

Changes in v7:
- At this point the obsolete .txt binding file only contains twl6030 related information, therefore it is deleted.

Changes in v6:
- Reworked 'interrupts' property to use a list of items with descriptions per reviewer feedback.

Changes in v5:
- Split combined twlxxxx-usb binding into a dedicated file for twl6030-usb per maintainer feedback.
- Used more accurate header for interrupt macros.
- Improved formatting in the examples.
- This patch also removes the old .txt file.

Changes in v4:
