PNPACPI: remove some code duplication
Factor out the duplicated switch from pnpacpi_count_resources() and pnpacpi_type_resources(). Remove the unnecessary re-initialization of resource->type and length from all the encode functions (id and length are originally set in the pnpacpi_build_resource_template() -> pnpacpi_type_resources() path).
