Carl-Daniel Hailfinger 1dfe0ff174 Add bus type annotation to struct flashchips
Right now, the annotation only differentiates between SPI and non-SPI.
Anyone who knows more about a specific flash chip should feel free to
update it.

The existing flashbus variable was abused to denote the SPI controller
type. Use an aptly named variable for that purpose.

Once this patch is merged, the chipset/programmer init functions can set
supported flash chip types and flashrom can automatically select only
matching probe/read/erase/write functions. A side benefit of that will
be the elimination of the Winbond W29EE011 vs. AMIC A49LF040A conflict.

Corresponding to flashrom svn r556.
