PNP: add pnp_init_resources(struct pnp_dev *) interface
Add pnp_init_resources(struct pnp_dev *) to replace pnp_init_resource_table(), which takes a pointer to the pnp_resource_table itself. Passing only the pnp_dev * reduces the possibility for error in the caller and removes the pnp_resource_table implementation detail from the interface. Even though pnp_init_resource_table() is exported, I did not export pnp_init_resources() because it is used only by the PNP core.
