Enable higher PWM frequencies for ESP32
LEDC peripheral of ESP32 allows higher PWM frequencies than the ESP8266. Higher frequencies come with reduced available bit depth (as by https://esphome.io/components/output/ledc.html). New max value of 50 kHz to include at least the frequency for 4-pin pwm fans and a bit more.
