If we do this, then the compatible field should probably be preceded with
"linux,", which would get stripped by of_register_i2c_devices().  This
would only be an interim measure until we can figure out some sort of
name registry via power.org.  Once that happens, non-"linux," compatible
fields could be looked up in an OF-to-linux table, or there could be a
way for i2c devices to specify OF matches in addition to driver name.
