coral: Use SKU ID to initialize motion_sensor_count
This CL adds the config option CONFIG_DYNAMIC_MOTION_SENSOR_COUNT and
SKU table which contains the form factor for all known SKUs. Once the
SKU ID is known, the variable motion_sensor_count is set based on
CLAMSHELL or CONVERTIBLE designation in the SKU table. If there isn't
a matching SKU ID in the table then motion_sensor_count will be
initialized to the ARRAY_LENGTH of motion_sensors.
BUG=b:38271876
BRANCH=None
TEST=Manual
Tested with Robo360 (SKU ID 71) and verified the motion sensor count
and that the motion senors were initialized in the EC console log.
[0.088188 Motion Sensor Init: count = 3]
[0.346097 Lid Accel: MS Done Init type:0x0 range:2]
[0.370386 Base Accel: MS Done Init type:0x0 range:2]
[0.386790 Base Gyro: MS Done Init type:0x1 range:1000]
Tested with Santa EVT (SKU ID 3) and verified motion_sensor_count is 0 and
no EC console messages showing sensor initialization failures.
