[Bug] Fix non-functional S3 wakeup / resume from suspense  (#19780)

* 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
