x86/pci/mrst: Use configuration mechanism 1 for 00:00.0, 00:02.0, 00:03.0
For real PCI devices 00:00.0, 00:02.0 and 00:03.0, there is either no PCI shim, or no guarantee of data correctness of offset 256-4k. So for whatever reason, Linux kernel should not do MMCFG PCI config access to those devices. Instead, always use configuration mechanism 1 for those devices. The 00:00.0, 00:02.0 and 00:03.0 devices are built-in single-function devices and are not PCI-PCI bridges, so this set of devices should be complete.
