chip/stm32/usb: Replace reset handler by generic event handler
Some USB interface handlers need to know when USB has been
successfully resumed after a wake event. For example, this is
useful so that HID keyboard can send the events at the right time.
BRANCH=none
BUG=b:35775048
TEST=Using USB HID keyboard patches to queue keys in a FIFO:
After USB autosuspends, press a single key and hold it. Without
this patch the endpoint data only gets reloaded on the _next_
event.
TEST=On hammer, I2C passthrough still works.
