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.
