ca4288df66 Change addr_decode test to use new io locations 
Instead of whatever was there before, the new io locations are ram, rom,
and the hex digits.

5d8c4aab44 Add USB code 
Adds the usb code that we got in ECE 385. It will not work now, and
parts that involve the timer are disabled. It does compile though, with
a few warnings.

The goal will be to add USB MSD support, which is not actually given to
us so I will have to do myself or find some other code to base it off
of.

aca739338a Remove spi_word and replace with spi_deselect 
Since the goal is to have the MAX3421E working, which uses multiple 8
bit transfers, we should support multiple 8 bit transfers instead of
trying to use 16 bit transfers.

When using spi_byte(), the device is automatically selected. After you
have made as many transfers as you want, you must deselect the device
with spi_deselect().

35973473d3 Change spi_write_byte to spi_byte 
the SPI module reads and writes at the same time. If you don't want to
write a value, then write all zeros or whatever the device you are
communicating with wants.

ee5271d955 Fix spi bug 
Was reading a value from x, shifting it, but then not writing it back.
This caused an infinite loop as it would never move on from the MSB.
