This does the following:

cd coreboot/src/southbridge
svn mv i82801ca i82801cx
svn mv i82801dbm i82801dx
svn mv i82801er i82801ex
svn copy i82801xx i82801bx
svn mv i82801xx i82801ax

Plus, fixing up the filenames in these directories and the romstage.c and
Kconfig files of the mainboards using those drivers.
Plus, switching the thomson ip1000 and rca rm4100 to the i82801dx driver.

There's a lot more to be done, like 
- adding device IDs for the ICH3 and newer drivers that have been kept in
  i82801xx so far
- drop the additional parts support from the ax and bx drivers.
