pci_host_generic: Enumerate resource ranges under bootverbose

Browse source 
Previously ranges were only enumerated for the FDT attachment but not
ACPI.  This commit moves the enumeration to the shared attach routine
so it is done for both.  While here, don't list empty ranges but do
include the resource type for each range.
