Fixes #10360 by enabling USB host on the USB host pads.
I did not enable it by default in board.c, maybe it should be like it is on the teensy 4.1 ?

Thanks @todbot for testing.

Test code:

import time, board
import usb, usb_host

port = usb_host.Port(board.USB_HOST_DP, board.USB_HOST_DM)

while True:
    for device in usb.core.find(find_all=True):
        print(device.product, device.manufacturer, hex(device.idProduct), hex(device.idVendor), time.monotonic())
    time.sleep(0.5)
