Fix up and document the AMD CS5530/CS5530A support

The previous code was pretty unreadable, undocumented and did some totally
unrelated things (such as mucking with the game port or port 0x92).

This version is tested with a 256 KB chip and should work for the
CS5530 and CS5530A.

Corresponding to flashrom svn r120 and coreboot v2 svn r2715.
