Add the ability to set Bus Pirate SPI speed via the command line
Example usage: flashrom -p buspiratespi:spispeed=2.6MHz,dev=/dev/foo flashrom -p buspiratespi:dev=/dev/foo,spispeed=2.6M Refactor programmer option parsing (this allows cleanups in other programmers as well). Increase SPI read size from 8 to 12 bytes (current single-transaction limit of the Bus Pirate raw SPI protocol). Add Bus Pirate to the list of programmers supporting 4 byte RDID. Add Bus Pirate syntax to the man page. Tested-by: Sean Nelson <audiohacked@gmail.com> Corresponding to flashrom svn r776.
