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().

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.

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.
