Input: atmel_mxt_ts - add missing compatible strings to OF device table
Commit af503716ac14 ("i2c: core: report OF style module alias for devices registered via OF") fixed how the I2C core reports the module alias when devices are registered via OF. But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its OF device ID table, so if a Device Tree is using a different one, autoload won't be working for the module (the matching works because the I2C device ID table is used as a fallback). So add compatible strings for each of the entries in the I2C device table.
