Karl Palsson c4cf904ef6 spi: drop misleading explicit baudrate comments
The SPI br parameter has always been the 3 bit fpclk divider field, and
was never a target or explicit bit rate.  Correct the comments, and drop
the duplicate commentary that wasn't included in the doxygen output
anyway.

Fixes: a7a3770d Add initial SPI code
