cheza: Configure ANX3429 interrupt as open-drain
This interrupt pin by default is a push-pull. It causes leak to EC VSPI
power during EC watchdog reset. As in our design, we use this interrupt
pin as open-drain. Should configure the register to make it open-drain.
BRANCH=none
BUG=b:112906111
TEST=Flashed the EC image to Cheza rev-2 board. Typed "reboot" command
and then EC reset properly.
