Fixes sigmaDeltaAttach() when another peripheral is already attached using the same pin

[SuGlider]

Description of Change

If a pin is attached to another peripheral and it is latter attached to SigmaDelta, it won't correctly detach the previous peripheral.
This PR fixes it, including when the DeltaSigma frequency is changed.

Tests scenarios

ESP32

#define PIN 2
void setup() {
  // Peripheral Manager will attach pin 2 UART (RX) - TX is the UART0 default pin.
  Serial.begin(115200, SERIAL_8N1, PIN);
  Serial.println("Serial pins - RX (pin 2) and TX (default) are attached");
  delay(1000);

  //Peripheral manage will detach pin 2 from UART (TX) and attach it to LEDC
  analogWrite(PIN, 100); // by default it will use 1KHz, 8 bits resolution
  Serial.println("Pin 2 is attached to LEDC");
  delay(5000);

  // Peripheral manager will detach pin 2 from LEDC and attach it to SigmaDelta
  sigmaDeltaAttach(PIN, 312500);
  sigmaDeltaWrite(PIN, 10);     // Start SigmaDelta
  Serial.println("Pin 2 is attached to SigmaDelta");
  delay(5000);
}

void loop() {}
