If DRDY signal is used, the interrupt status needs to be cleared at FIFO reset in order to make DRDY go back inactive. Otherwise there won't be a falling edge interrupt at the next sample. Signed-off-by: Jukka Laitinen <[email protected]>

Disable I2C to make sure that the sensor doesn't switch to that by accident Signed-off-by: Jukka Laitinen <[email protected]>
As the sensor can directly report the amount of samples in the fifo, use it to simplify the logic. Also combine the fifo empty/fifo overflow checks for interrupt and polling modes. Signed-off-by: Jukka Laitinen <[email protected]>

Adds a fix for ICM40609D interrupt (DRDY) driven mode, and cleanups for FIFO handling.
Without the first patch in this set, the DRDY mode is not working at all.
Tested on custom HW, using the sensor both in DRDY and polling mode, by using perf, listener and uorb top. Checked that values are sane, there are no extra errorsr in "perf" and uorbs are published at the desired rate.
