Patrick Georgi 10bbfda839 libpayload/usb: wait a millisecond to work around device bugs
Some USB sticks seem to send a NAK at a place where they mustn't
by spec, leading to a controller side error condition.

To avoid it, wait a millisecond which is enough to get past the
NAK condition. That delay only happens on device discovery so it
won't affect boot time by more than 1ms per device.

BUG=chromium:414959
BRANCH=none
TEST=depthcharge recognizes a Lexar 16GB USB stick after applying
this change.
