Fix this issue by retrieving the chip info block CRC before the check.

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).
