UDI API.
The callbacks within this structure are called only by USB Device Controller (UDC)
The udc_get_interface_desc() can be use by UDI to know the interface descriptor selected by UDC.

void(* udi_api_t::disable)(void) |
Disable the interface.
This function is called when this interface is currently active, and
bool(* udi_api_t::enable)(void) |
Enable the interface.
This function is called when the host selects a configuration to which this interface belongs through a Set Configuration request, and when the host selects an alternate setting of this interface through a Set Interface request.

uint8_t(* udi_api_t::getsetting)(void) |
Returns the current setting of the selected interface.
This function is called when UDC when know alternate setting of selected interface.
bool(* udi_api_t::setup)(void) |
Handle a control request directed at an interface.
This function is called when this interface is currently active and the host sends a SETUP request with this interface as the recipient.
Use udd_g_ctrlreq to decode and response to SETUP request.
