Hi Martin,

When u-boot chainloads an EFI bootloader such as iPXE, we want to have already initialized the PCI subsystem so that network driver is loaded and ready to use by the bootloader.
This change slows down boot from emmc/sd-card where scanning for pci devices typically is unnecessary.
If pci must be initialized and scanned before an EFI app is started to find pci network controllers, then pci should probably be initialized by the efi bootmeth, not by enabling CONFIG_PCI_INIT_R for a single board.
