After running with this version of drivers and dumping registers, I got the following result: BMI160_INT_OUT_CTRL_ADDR UINT8_C(0x53) :: 0x88

Was stuck for a while during development for the BMI160 sensor due to using the
BMI160_INT_CHANNEL_BOTHdefine which can be found in: https://github.com/BoschSensortec/BMI160_driver/blob/44f0df94d6b000a821afd7ed31c432bc677cd723/bmi160_defs.h#L1004The define is there, however when configuring the sensor, the code for configuring both interrupt channels is lacking in the driver library. Since the current library implementation defaults to configuring interrupt channel 2 for every value other than
BMI160_INT_CHANNEL_1, it will configure interrupt channel 2 - not both - when setting int_channel toBMI160_INT_CHANNEL_BOTH. This is very misleading.This PR implements support for both interrupt channels for the sensor, and it implements a guard statement to return an error code in case an invalid configuration is provided instead of defaulting to interrupt channel 2.
After testing my fork of the library with these changes on our device I get the following value in the INT_OUT_CTRL register (0x53):
This means that the output enable for both interrupt channel 1 and 2 is set to enabled. For more details on this, see the BMI160 datasheet on page 63.
