Input: atmel_mxt_ts - Only warn when config CRC does not match

The CRC will not match if the config has been upgraded (ie the info_crc
doesn't match), also there are new chips with objects included in the CRC
which are previous to T7, and some chips without T7, which means that this
code must only produce a warning until those issues are dealt with.
