pci: Add ability to re-enumerate PCI buses
Add a new 'pci enum' command which re-enumerates the PCI buses. This
command is enabled via the CONFIG_CMD_PCI_ENUM define and can be useful
in boards with FPGAs connected via PCI/PCIe, boards that support PCI
hot-plugging, or during PCI debug.
Also enable the 'pci enum' command for X-ES's Freescale-based boards.
