A parsing problem might mean we ignore some resources the device is using, or we might not be able to change its resources. But we should still take note of anything we *could* parse correctly.

This removes the pnp_resource_table arguments to make it clear that these methods only operate on the specified pnp_dev.

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.
