ARM: kirkwood: Unbreak PCIe I/O port

The support for the 2 pcie port of the 6282 has broken i/o port by switching
*_IO_PHYS_BASE and *_IO_BUS_BASE. In fact, the patches reintroduced the same
bug solved by commit 35f029e2514be209eb0e88c7d927f3bcc42a5cc2.
So, I'm adding back *_IO_BUS_BASE in resource declaration and fix definition
of KIRKWOOD_PCIE1_IO_BUS_BASE. With this change, the xgi card on my t5325 is
working again.
