Initial SPI Polling implementation.
Initial commit of a polling-based SPI driver. The driver is limited to
synchronous, blocking sends and a 8-bit data frame format. Tested on
SPI1 and SPI2.
Other peripherals are temporarily disabled, and the rx function
is untested until I find a good peripheral to test everything on.
