Fixed DMA and INT bugs

- Fixed indexed task notifications for INT and DMAf for both sensors
- Fixed the INT debugger startup freeze (added != NULL check in
callbacks)
- Fixed DMA notifications not being read properly/too early
- Changed IMU INT configure/enable function as one
- Added proper DMA checking in IMU calibration
