device_util,agesa/family14: Do not consider unassigned resources in find_pci_tolm()
This change updates find_pci_tolm() to not consider any unassigned
resources. This is achieved by adding the following checks:
1. Call search_bus_resources() with mask set to IORESOURCE_MEM |
IORESOURCE_ASSIGNED.
2. In the callback tolm_test, check that the new resource selected has
a non-zero size.
This change is being made so that the resource allocator does not have
to set the IORESOURCE_ASSIGNED flag for marking a resource as
invalid.
