Log:
flashrom: Remove dead M-Systems Disk on Chip code
DOC support has been disabled by default for many years. The write function
does nothing but print text. It has a call to write_page_md2802() commented
out, but that function does not exist. This is dead code with ugly #ifdefs.
Updates README to reflect that there was a time when there was code, but it
didn't work. Removes M-Systems #defines and also includes svn rm msys_doc.*

Disk on Chip support
--------------------
-Disk on Chip support is currently disabled since it is considered unstable.
-Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.
+Disk on Chip support was removed from flashrom in r3380. It had already
+been disabled by default in flashrom for several years because the code
+was considered unstable and incomplete. The products intended to work
+have been End-Of-Lifed by the manufacturer for a long time.
