driver: tcs3400: Report ODR for RGB sensor
To be able to send data to the host, the oversampling ratio must be
non-zero. It implies:
- the host send a set frequency request for the RGB sensor
- the EC use the frequency from the clear sensor to calculate the
RGB sensor oversampling ratio
BUG=b:172343923
BRANCH=kukui,hatch,volteer
TEST=On Volteer, in calibration mode, check we get samples from the RGB
sensor.
