[gen3] hal: fix gpio glitch

[XuGuohui]

Problem

pinMode(pin, OUTPUT_OPEN_DRAIN) or pinMode(pin, OUTPUT_OPEN_DRAIN_PULLUP) cause I/O glitch.

Solution

When configuring a pin as OUTPUT_OPEN_DRAIN or OUTPUT_OPEN_DRAIN_PULLUP using pinMode(), it sets the output value to 1 to release the pin control.

Steps to Test

Flash the following test app and use logic analyzer or oscilloscope to monitor the state of the pin being configured

Example App

#include "application.h"

SYSTEM_MODE(SEMI_AUTOMATIC);

void setup() {
    delay(5s);
    pinMode(D0, OUTPUT_OPEN_DRAIN); // or OUTPUT_OPEN_DRAIN_PULLUP
}

void loop() {
}
