Subject: [PATCH] fix(usb): Prevent unexpected USB disconnection caused by USB
 SOF (#3070)

ZMK doesn't use SOF. Disable this to prevent unexpected USB
disconnection. The disconnection is observed under 3 circumstances on a
Linux host:

1. Keyboard just performed a firmware upgrade and USB is kept connected.
2. Keyboard is woken from USB power source and USB is kept connected.
3. Keyboard is connected when host is booting, and when Linux is just
   initialized.

Disabling SOF processing will not affect boot protocol switching.

Tested on Makerdiary M60.
