arm: zynq: zybo z7: fix MIO init issue
The board has two push button connected to MIO pins 50 and 51, which have a pull-down resistor and are connected to 1.8V when pressed. These two pins are wrongly initialized with internal pull-up enabled so they are reported as 1 all the time with no change when pressed. Disable the internal pull-up to fix the issue.
