common: host: Do no report sensor when motion_sensor_count set to 0.
On some machine (kefka), the number of sensor is set at run time to 0.
Be sure we do not report that sensors or sensor FIFO are available to
the kernel.
BRANCH=glados
TEST=On kefka, check no iio devices are reported, even when sensor FIFO
is in the firmware.
On Sabin, check all expected IIO devices are present.
BUG=b:27849483
