ESP32-S3 USB peripheral freezes after light sleep at 40MHz (IDFGH-14711)

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

What is the expected behavior?

The USB peripheral working normally after returning from light sleep. (I know clock to USB is gated during sleep)

What is the actual behavior?

At 40MHz CPU frequency, USB-OTG works fine. However, after entering light-sleep and resuming, the USB peripheral is frozen. It doesn't matter if the peripheral was initialized or not. If uninitialized, the driver_install function will stall - if it was already initialized, the peripheral just stops handling any USB events.

Briefly switching to 80MHz and back to 40MHz after wakeup "fixes" the issue.

Steps to reproduce.

Here is a reproducuction using the tusb_hid sample: https://github.com/dbeinder/esp32s3-tusb-hid
Changes to the sample: dbeinder/esp32s3-tusb-hid@4a43223

tinyusb_driver_install() will stall in reset_core() in dwc2_common.c - see watchdog backtrace.

Uncommenting the two lines to switch to 80MHz and back to 40MHz makes the initialization work again.
