UefiPayloadPkg/Pci: Use the PCIE Base Addr stored in AcpiBoardInfo HOB

Browse Source 
Today's UefiPayloadPkg always uses 0xE0000000 as the PCIE base address
and ignores the value set in AcpiBoardInfo HOB created by the boot
loader. This makes the payload binary cannot work in environment
where the PCIE base address set by boot loader doesn't equal to
0xE0000000.

The patch enhances UefiPayloadPkg so that the PCIE base address
set by boot loader in the AcpiBoardInfo HOB is used.
