input: touchscreen: ad7879: fix default x/y axis assignment
The measurements read from the controller which are temporarly stored
in conversion_data, are interpreted wrong. The first measurement X+
contains the Y position, and the second measurement Y+ the X position
(see also Table 11 Register Table in the data sheet).
The problem is already known, the change 6680884a4420 ("Input: ad7879
- add option to correct xy axis") introduced a swap option. However,
the meaning of this boolean was inverted since the underlaying values
were already swapped. With this change, swap_xy = true actually swaps
the two axis.
