Vincent Palatin e156e014dd g: slightly optimize boot on USB resume ...

Save a small amount of time when the USB resume is making the chip boot
from deep-sleep by removing the verbose serial traces in main and
increasing the usb initialization priority.

This brings us from borderline timings wrt the USB specification to a
reasonable margin.

BRANCH=none
BUG=b:38160821
TEST=run on hotelgolf, go to deep-sleep on USB-suspend.
On USB resume, measure the time from CPU boot to the end of usb_init
using the CPU cycle count. We are shaving 1.3ms.
