PNP: remove pnp_resource_table from internal get/set interfaces

When we call protocol->get() and protocol->set() methods, we currently
supply pointers to both the pnp_dev and the pnp_resource_table even
though the pnp_resource_table should always be the one associated with
the pnp_dev.

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