[PATCH] input:ad7879-i2c use swapped varient of i2c_smbus_read_word_data

This varient was introduced in
i2c: boilerplate function for byte swapped smbus_write/read_word_data

This also has the side effect of ensuring any errors from the i2c
read and no longer mangled.

The patch introducing this swapped function is working its way through the i2c
tree.
