Add 'RRIOT_F722' target

[ws998116]

We have completed development and testing for this board and would like to add the target config.

[ws998116]

One issue that we've found is in the Receiver tab, the Telemetry setting shows up twice.

i'm not certain what causes dual telemetry toggles. please try nightly configurator https://github.com/betaflight/betaflight-configurator-nightlies/releases or https://app.betaflight.com in Chrome.

Dual telemetry shows up in case of a local build which is fixed in https://app.betaflight.com

• Does this FC not have a LED_STRIP pin?

• Target is missing gyro interrupt pin.

• No timer for camera control pin.

Please provide the schematic in the appropriate manufacturer channel on the Betaflight Discord. Contact @sugaarK for access.

No, we do not have an LED_STRIP pin.

• Target is missing gyro interrupt pin.

I have added the gyro interrupt pin define.

• No timer for camera control pin.

I am having trouble adding this. The camera control pin is PC4, and I can't seem to add a timer to this pin (C04) using the CLI.

[haslinghuis]

Pin C4 does not have timers.

[ws998116]

No timer for camera control pin.

Pin C4 does not have timers.

Are we required to have a timer for the camera control pin?

[haslinghuis]

Yes camera control seems to need a timer.
