Automatically unmap physmap()s

Browse Source 
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.
