Subject: [PATCH 2/7] resource: Rename find_resource() to find_empty_resource_slot()

Rename find_resource() to find_empty_resource_slot() to better describe
what the functions does. This is a preparation for exposing it beyond
resource.c which is needed by PCI core. Also rename the __ variant to
match the names.
