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.

Corresponding to flashrom svn r776.
