Subject: [PATCH 4/5] Add map pgoff to python dictionary based on MAPPING_TYPE
From: "steve.c.clevenger.ampere" <scclevenger@...amperecomputing.com>
Add map_pgoff parameter to python dictionary so it can be seen by the
python script, arm-cs-trace-disasm.py. map_pgoff is forced to zero in
the dictionary if file type is MAPPING_TYPE__IDENTITY. Otherwise, the
map_pgoff value is directly added to the dictionary.
