motion: remove load_fifo
To prevent invalid timestamping, call load_fifo only when we get a FIFO
interrupt.
In consequence, remove load_fifo entry point and only process fifo
inside the IRQ.
Add helper function to know when we are in forced mode (the EC needs to
periodically read sensor data or interrupt driven).
