Extend the previous operation of finding the resource table in the ELF with the extra step of populating the rproc struct with a copy and the size. This allows drivers to override the mechanism used for acquiring the resource table, or omit it for firmware that is known not to have a resource table. This leaves the custom, dummy, find_rsc_table implementations found in some drivers dangling.
