* [Core] Allow customizing PWM frequency
Some frequencies can cause audible noise. Changing the frequency
eliminates that.

GCC 13 needs the same workaround as GCC 12.
To avoid having to maintain an ever-growing list of broken versions
apply the workaround wherever it can be used.
If at some point a fixed version of GCC is released the workaround can
be disabled for those fixed versions.
See #17064
Previously, if the user tried to use `#define AUDIO_MAX_SIMULTANEOUS_TONES 1` to conserve CPU time, their firmware would fail to build with this error:
```
platforms/chibios/drivers/audio_dac_additive.c:91:73: error: excess elements in array initializer [-Werror]
91 | static float active_tones_snapshot[AUDIO_MAX_SIMULTANEOUS_TONES] = {0, 0};
| ^
```
This also affected the preset `#define AUDIO_DAC_QUALITY_VERY_HIGH`, which called up only one simultaneous tone at 88200 Hz.
* Update ChibiOS-Contrib for USB suspend fixes
* Remove S3 wakup workaround
ChibiOS OTGv1 driver has a remote wakeup bug that prevents the device to
resume it's operation. 02516cbc24647f522eee975e69cc0c8a925470eb
introduced a hotfix that forcefully restarted the usb driver as a workaround.
This workaround broke multiple boards which do not use this driver /
peripheral. With the update of ChibiOS this hotfix is now obsolete.
* Remove restart_usb_driver overrides
they are no longer necessary as the workaround is not needed anymore
for stm32f4
* Remove unused RP_USB_USE_SOF_INTR defines
The SOF interrupt is enabled dynamically by the RP2040 usb driver
The `adc_read()` code for STM32F0xx expects to get the 0-based channel
number in `mux.input`, but the `pinToMux()` code for STM32F0xx was
attempting to pass the CHSELR bit mask in that field, which resulted in
selecting a wrong channel, therefore `analogReadPin()` did not work
properly for the STM32F0xx chips. Fix `pinToMux()` to put the channel
number in that field (this matches the behavior for other supported
chips and also allows selection of channels 16...18, which can be used
to access the builtin temperature, reference voltage and VBAT sensors).
