c8872c1088 sw: don't clear OUT buffer during usb_recv 
If there is data already in the OUT buffer, don't throw it away.

This was necessary when using `epfifo` due to the way it shared OUT and
SETUP packets.  However, it is causing reliability issues with eptri.

acdccf5f98 booster: change magic number for booster 
Since the USB and flash communication layers are different, change the
magic number for booster.  This will prevent previous versions of foboot
from trying to launch our updater with the wrong version.

0156e211eb foboot: don't re-enter updater when spi id doesn't match 
Consult the spi_id prior to jumping to the updater.  This will
ensure that if the wrong image is flashed, it won't get
re-executed during a reboot.

c6c3ae8c47 spi: speed up bit banging and special case everything 
This patch significantly improves SPI throughput by avoiding
many duplicated writes.  For example, we now only adjust the MISO
direction once during every byte rather than for every bit.

This improves the time it takes to upload a 128 kilobyte file from 29
seconds to 6 seconds.
