iio: imu: inv_mpu6050: Add support for ICM-20608-D

Browse source 
The difference between the ICM-20608-D and the other ICM-20608
variants is the addition of a DMP (Digital Motion Processor) core.
This difference is deemed substantial enough to change the WHOAMI
register value.
Since this driver doesn't currently acknowledge the exisence of
something like a DMP core, simply copy ICM-20608 except for the
aforementioned WHOAMI register.
