mpc83xx: PCIe: Don't start bus enumeration at 0
Currently we assign first_busno = 0 for the first PCIe hose, but this
scheme won't work if we have ordinary PCI hose already registered (its
first_busno value is 0 too).
The old code worked fine only because we have PCI disabled on
MPC837XEMDS boards in stand-alone mode (see commit 00f7bbae92e3b13f2b3
"mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards").
But on MPC837XERDB boards we have PCI and PCIe, so the bug actually
triggers.
So, to fix the issue, we should use pci_last_busno() + 1 for the
first_busno (i.e. last available busno).
