[0/2] staging: iio: imu: Add CEVA BNO08x through the staging tree

Hello,
   this series adds support for the CEVA BNO08x Sensor Hub through the staging
tree.

The driver currently only support reading a rotation vector in quaternion, which
is just one of the many features supported by the device.

What's relevant here is the protocol handling part, which is used to exposed a
triggered buffer and direct access IIO interfaces. The BNO08x family implements
a packed-based protocol which requires parsing on the driver side. This driver
implements such parsing routine by copying the full received packets and
synchronize the possible multiple consumers which might want to access the data.

Sent through the staging tree as the HW platform I used to test is not available
anymore and I cannot guarantee maintainership of the driver.

However I hope the driver can serve as a useful reference for future
developments.

Thanks
