soc/amd/stoneyridge: Move GPIO support to common

The banked GPIO functionality in the AcpiMmio block has been consistent
since the Mullins product.  Move the basic support into a common
directory.

Each product's pin availability, MUXes, and other details must remain
specific to the product.

The relocated source also drops the weak configure_gevent_smi() that
reports SMI is not available.  The stoneyridge port relies on SMI
to do its initialization, similar to modern soc/intel devices.  This
is the plan for future soc/amd ports, so make a missing function a
build error instead of a runtime warning.
