The purpose of pci_early_bridge_init() is to temporarily configure PCIe rootport (or PCI bridge) on bus 0 to configure PCI device BARs on the secondary bus. Currently used and tested only with UART_OXPCIE. Since those BARs do not reset on stage changes, it is not necessary to redo those steps for verstage or postcar. Note that the option does not really work with many of the later platforms where PCIe pins/links/lanes are configured late in FSP-M or similar blob.
