vc/amd/opensil/stub: add stub MPIO driver

Add a stub MPIO chip driver to the openSIL stub code, so that the
devicetree entries needed for the MPIO chip can already be added to the
mainboard's devicetree files. This driver won't do anything, but still
allows the register settings in the devicetree to be set to make
switching over to the actual openSIL code and the corresponding glue
code easier.
