dm: pci: Allow delaying auto-config until after relocation
At present PCI auto-configuration happens in U-Boot both before and after relocation. This is a waste of time and may mess up static addresses used in board_init_f(). Adjust the code to supporting doing auto-configuration once, after relocation, under control of a device-tree property. This is needed for Apollo Lake for debugging the silicon-init code. Once the UART is moved to a different MMIO address the debug UART does not work and any debug output in Apollo Lake's arch_fsp_init_r() causes a hang.
