### Problem with mbed::PwmOut with Portenta H7

IDE: Arduino IDE 1.8.15

Board: Portenta H7 and Portenta Breakout board

mbed::PwmOut was working perfectly in ArduinoCore-mbed 2.2.0 but since update 2.3.1 it is not possible to make two PWM channels work simultaneously. Not yet tested with more channels.

Test sketch:

#include "mbed.h"

using namespace mbed;

PwmOut pwm_a(PA_8);
PwmOut pwm_b(PC_6);

void setup() {

  pwm_a.period_us(5000);
  pwm_a.pulsewidth_us(50);

  pwm_b.period_us(5000);
  pwm_b.pulsewidth_us(50);

}

void loop() {

}

Output results with version 2.2.0 in pins PWM0 (yellow) and PWM1 (blue):

Output results with version 2.3.1 in pins PWM0 (yellow) and PWM1 (blue):

As we can see PWM0 channel is not generating the setted pulse.

Please let me know if you need more information or help.
