From: Ravi Patel <ravip...@xilinx.com>
GPO1[2] is set to 0 at startup of PMU ROM. MIO34 pin (connected to LTC
kill signal) is mapped to GPO1[2] by fsbl. Because of weak pull-up
register on MIO34, 1 to 0 transition occurs which results into cut down
of board power. This fix was provided in zcu100-poweroff-support patch.
