Fix the DOS port

Browse Source 
Now the DS selector limit is set to 4GB and all mmio accesses goes
through DS, the 1:1 mapping is fixed so the _DS base is taken onto
account. Plus is that the hwaccess.c needs no change and memcpy etc can
be used on mmaped space.

Corresponding to flashrom svn r995.
