Changed pinMode() default interrupt type DISABLED to previously set

[P-R-O-C-H-Y]

Description of Change

pins default configuration has intr_type = GPIO_INTR_DISABLE
With this implementation, it will set the intr_type to previously set intr_type. It will no longer disable interrupt, when pinmode is called multiple times on same pin with interrupt enabled.

There is no option to get pin config from ESP-IDF API, that's why I made this implementation.

Tests scenarios

//To trigger ISR, connect GPIO 19 to GND.

uint32_t interrupt_count = 0;

void IRAM_ATTR pin_interrupt(void *arg) {
  interrupt_count++;
  pinMode(19, INPUT);
  //attachInterruptArg(19, pin_interrupt, 0, CHANGE);
}

void setup() {
  pinMode(19, INPUT);
  attachInterruptArg(19, pin_interrupt, 0, CHANGE);
}

void loop() {
  ESP_LOGD("loop", "interrupt count %d", interrupt_count);
  delay(500);
}

Indentation issue here :)

Wierd, I dont see that in GitHub Deskto / VS Code or GitHub integrated editor.

Replaced tabs with spaces, should be fine now :)
