Refine SPI bitbanging
Change the SPI bitbanging core to fix a subtle bug (which had no effect so far) and to make integration of the RayeR SPIPGM and Nvidia MCP6x/MCP7x SPI patches easier. Kill a few global variables and require explicit initialization of bitbanging delay. A big to Johannes Sjölund for testing an earlier version of the code as part of the Nvidia MCP6x/MCP7x SPI bitbanging patch. Corresponding to flashrom svn r1085.
