Introduce async DEVX obj query API to get the command response back to user space once it's ready without blocking when calling the firmware. The event's data includes a header with some meta data then the firmware output command data. The header includes: - The input 'wr_id' to let application recognizing the response. The input FD attribute is used to have the event data ready on. Downstream patches from this series will implement the file ops to let application read it.
