CorebootPayloadPkg/FbGop: Locate correct framebuffer device
BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=1628 Current FbGop driver might bind to the wrong PCI device if a system has multiple PCI display devices. The original idea was to reuse the generic GraphicsOutputDxe to address this issue. However, after exploring different approaches discussed in the bugzilla, it turned out that the best approach is to enhance the current FbGop driver to match the PCI device BAR value with the framebuffer base address. This patch implemented this enhancement by selecting the PCI device with matched framebuffer base in its PCI BAR. This has been tested with coreboot on QEMU and Apollo Lake platform.
