Dear Anatolij Gustschin,

PCI cards might need some time after reset to respond. On some boards (mpc5200 or mpc8260 based) the PCI bus reset is deasserted at pci_init_board() time, so we currently can not use available "pcidelay" option for waiting before PCI bus scan since this waiting takes place before calling pci_init_board(). By moving the pcidelay code to the new location using of the "pcidelay" option is possible on mpc5200 or mpc8260 based boards, too.
Since pci_hose_scan() could be called multiple times, restrict the function to wait only during its first call and to ignore pcidelay for any further call (as pointed out by Matthias).

Changes since first version:
- extend to wait only during initial pci_hose_scan() call as pointed out by Matthias
