eve: Enable Sensor FIFO
Enable to FIFO to allow ARC++ sensor support and sensor tests.
BUG=chrome-os-partner:59144
BRANCH=eve
TEST=On an eve machine, check the ring sensor is receiving data:
cd /sys/bus/iio/devices/iio:device0 # cros-ec-ring
for i in scan_elements/*_en ; do echo 1 > $i ;done
echo 1024 > buffer/length
echo 1 > buffer/enable
cd /sys/bus/iio/devices/iio:device1 # cros-ec-accel
echo 1000 > sampling_frequency # 1s
echo 25000 > frequency # 25Hz
Check we are receiving data with:
od -x /dev/iio\:device0&
