Returns

• Repeated HDMI enablement returns a success message.
• This API does not support the multi-process scenario.
• This API must be called in pairs with the hi_mpi_hdmi_close API. That is, after the hi_mpi_hdmi_open function is called, the hi_mpi_hdmi_close API needs to be called when the hi_mpi_hdmi_open function exits. In addition, the values of hi_hdmi_id in the input parameters of the two APIs must be the same.
