PNP: convert encoders to use pnp_get_resource(), not pnp_resource_table

PNP: convert encoders to use pnp_get_resource(), not pnp_resource_table

This removes more direct references to pnp_resource_table.  This
path is used when telling a device what resources it should use.

This doesn't convert ISAPNP because ISA needs to know the config
register index in addition to the resource itself.
