[PATCH V2] input:ad7879-i2c use swapped varient of i2c_smbus_read_word_data

[Jonathan Cameron <jic23@cam.ac.uk>]

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.

V2: include the write function as pointed out by Michael Hennerich.

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