Split internal.c into internal.c and hwaccess.c

Browse Source 
Linking in support for the internal programmer doesn't make sense if you
only need hardware (ioport, memory) access.

Note: This patch was created by "svn cp internal.c hwaccess.c" and then
removing stuff from both files. That's why you can't apply the patch
as-is before running the svn cp.

Corresponding to flashrom svn r898.
