Subject: [PATCH v2 17/19] remotecore: core: Add resource table pointer argument to rproc_handle_resource

In current version, rproc_handle_resource use rproc->table_ptr
as default resource table, fixing table to handle.
This patch adds resource table as function argument to have more
flexibility and be able to handle resources from any table.
