Automatically unmap physmap()s
Similarly to the previous PCI self-clean up patch this one allows to get rid of a huge number of programmer shutdown functions and makes introducing bugs harder. It adds a new function rphysmap() that takes care of unmapping at shutdown. Callers are changed where it makes sense. Corresponding to flashrom svn r1714.
