This is the bitbanging SPI driver infrastructure

If you want support for a particular piece of hardware, just fill in
a few functions in spi_bitbang_master_table. That's it.
On top of this, the RayeR SPI flasher should be supportable in ~20 LOC.

Tested, trace looks OK.

Corresponding to flashrom svn r736.
