mfd / platform: cros_ec: Add sensor_count and make check_features public
Add a new function to return the number of MEMS sensors available in a
ChromeOS Embedded Controller. It uses MOTIONSENSE_CMD_DUMP if available
or a specific memory map ACPI registers to find out.
Also, make check_features public as it can be useful for other drivers
to know what the Embedded Controller supports.
