REF: https://bugzilla.tianocore.org/show_bug.cgi?id=720
The current implementation assumes there is only one hotplug resource
padding for each resource type. It's not true considering
DegradeResource(): MEM64 resource could be degraded to MEM32
resource.
The patch treat the resource paddings using the same logic as
treating typical/actual resources and the total resource of a bridge
is set to the MAX of typical/actual resources and resource paddings.
