iio / platform: cros_ec: Add cros-ec-sensorhub driver
Similar to HID sensor stack, the new driver sits between cros-ec-dev
and the IIO device drivers:
The EC based IIO device topology would be:
iio:device1 ->
...0/0000:00:1f.0/PNP0C09:00/GOOG0004:00/cros-ec-dev.6.auto/
cros-ec-sensorhub.7.auto/
cros-ec-accel.15.auto/
iio:device1
It will be expanded to control EC sensor FIFO.
