sh-pfc: Remove configuration dry-run and free
The purpose of the dry-run is to ensure that a pin about to be
configured isn't in use. However, the current implementation is a no-op.
This proves that the dry-run isn't essential. Remove it.
Freeing configuration then becomes a no-op as well. Remove it.
