-----------
UefiPayloadPkg: Fix PciHostBridgeLib
Don't assume a 64bit register always holds an address greater than 4GB.
Check the value in the register and decide which Aperature it should be
assigned to.
Fixes assertion
"ASSERT [PciHostBridgeDxe] Bridge->MemAbove4G.Base >= 0x0000000100000000ULL".
Tested with coreboot as bootloader on platforms that have PCI resource
above 4GiB and on platforms that don't have resource above 4GiB.
