help
USB host class driver for vendor-specific serial devices
that use bulk endpoints for data transfer. Targets modem
devices such as the Quectel EG916Q which expose vendor-class
interfaces for AT/PPP communication.

Exposes the Zephyr UART async API so that higher-level
subsystems (modem, PPP) can use the device transparently.
