Synchronize vPOD PDF and IDF

This change scynronizes PDF and IDF files for vPOD to prepare
for moving hardware configuration files to infra/hwconfig repo.

From this point onward, the changes that are done to PDF and IDF
in infra/engine repo should be done in infra/hwconfig repo until
we completely switch to infra/hwconfig repo in order not to impact
the development work. Once the switch is done, vPOD PDF and IDF
should be removed from infra/engine repo.
