device: Add IORESOURCE_ABOVE_4G flag to PCI64 resources
When a PCI resource is marked as 64-bits, the IORESOURCE_ABOVE_4G flag
needs to be passed to the v4 allocator to ensure that the resource will
be allocated in a range large enough to succeed.
BUG=b:214443809
TEST=agah can successfully allocate all of the Nvidia GN20 BARs
