iio: cros_ec: Trace EC sensors command
For debugging, add tracing for EC_CMD_MOTION_SENSE_CMD command:
- decode the name of the subcommand
- provide internal information for the most common sub-commands:
setting range, frequency, EC probing frequency, ...
- display return status.
When enabled, the tracing output is similar to:
/sys/kernel/debug/tracing # echo 1 > events/cros_ec/enable ; echo 1 > tracing_on ; cat trace_pipe | grep MOTIONSENSE_CMD_SENSOR_ODR
SensorDeviceImp-814 [003] ..... 686.176782: cros_ec_motion_host_cmd: MOTIONSENSE_CMD_SENSOR_ODR, id: 1, data: 200000, result: 4, return: 12500
