[PATCH 1/2] i2c: cros-ec-tunnel: Add of match table

[Sjoerd Simons]

To enable the cros-ec-tunnel driver to be auto-loaded when build as a
module add an of match table (and export it) to match the modalias
information passed on to userspace as the Cros EC MFD driver registers
the MFD subdevices with an of_compatibility string.
