Pull Request Overview
This PR adds support for the ESP32-H4 microcontroller to TinyUSB by integrating it into the existing DWC2 USB driver infrastructure. The ESP32-H4 is treated similarly to other ESP32 variants (S2, S3) that use the DWC2 USB controller.
- Defines the new MCU option constant for ESP32-H4
- Configures DWC2 USB controller parameters and register field mapping for H4
- Enables H4 in USB initialization and PHY setup code paths
