RFC: [MIPS] BCM1480HT set mips_io_port_base

[Bjorn Helgaas <bjorn.helgaas@hp.com>]

I don't see anywhere that BCM1480HT sets mips_io_port_base (but maybe
I missed it).  We *do* set bcm1480ht_controller.io_map_base, so pci_iomap()
should work, but without mips_io_port_base, I don't think inb() et al.
will work.
