ChromeOS EC can report activity information derived from the
accelerometer:
- Reports on-body/off-body as a proximity event.
- Reports significant motion as an activity event.
This new sensor is a virtual sensor, included only when the EC firmware
is compiled with the appropriate module.

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

Add a IIO driver that reports the angle between the lid and the base for
ChromeOS convertible device.
Tested on eve with ToT EC firmware.
Check driver is loaded and lid angle is correct.

Add the core functions to be able to support the sensors attached behind
the ChromeOS Embedded Controller and used by other IIO cros-ec sensor
drivers.
The cros_ec_sensor_core driver matches with current driver in ChromeOS
4.4 tree, so it includes all the fixes at the moment. The support for
this driver was made by Gwendal Grignou. The original patch and all the
fixes has been squashed and rebased on top of mainline.
