This adds the device-tree bindings for the Bosch Sensortec BMI088 IMU,
the accelerometer part.

Signed-off-by: Mike Looijmans <redacted>

Just the issue the build bot found.  Otherwise looks good to me.

As per Rob's build bot you need.

spi-max-frequency: true

If that's all that comes up and Rob is happy with this I can fix that up whilst
applying.  Please try to run the checks suggested in Rob's build bot message
before submitting binding patches though.

There'll be a v8 it seems, so I've already added it. Seems that I need 
to upgrade those definition files every day...
