The Atmel maxtouch DT binding documents that the compatible string for
the device is "atmel,maxtouch" but the I2C core always reports a module
alias of the form i2c:alias where alias is the compatible string model:

MODALIAS=i2c:maxtouch

But there isn't maxtouch entry in the I2C device ID table so when the
i2c:maxtouch MODALIAS uevent is reported, kmod is not able to match the
alias with a module to load:

alias:          of:N*T*Catmel,maxtouch
alias:          i2c:mXT224
alias:          i2c:atmel_mxt_tp
alias:          i2c:atmel_mxt_ts
alias:          i2c:qt602240_ts

So add this entry to the I2C device ID table to allow the module to be
autoloaded when the device is registered via OF.
