Daisuke Nojiri 0988c5875f Nami: Toggle Anx7447 reset line at start-up ...

This patch configures the GPIO pin connected to the reset pin of
Anx7447 as push-pull low. When the EC start up from reset, it
pulls it high, waits for 1 msec, then pulls it low. This allows the
tcpc to recover from a hang and guarantees it to start from a known
state.
