platform/chrome: wilco_ec: Add version sysfs entries
Add the ability to extract version information from the EC.
Example Output:
$ cd /sys/bus/platform/devices/GOOG000C:00
$ tail build_date build_revision version model_number
==> build_date <==
04/25/19
==> build_revision <==
d2592cae0
==> version <==
00.00.14
==> model_number <==
