MIPS: SGI-IP27: abstract chipset irq from bridge
Bridge ASIC is widely used in different SGI systems, but the connected
chipset is either HUB, HEART or BEDROCK. This commit switches to
irq domain hierarchy for hub and bridge interrupts to get bridge
setup out of hub interrupt code.

MIPS: SGI-IP27: use generic PCI driver
Converted bridge code to a platform driver using the PCI generic driver
framework and use adding platform devices during xtalk scan. This allows
easier sharing bridge driver for other SGI platforms like IP30 (Octane) and
IP35 (Origin 3k, Fuel, Tezro).

[paul.burton@mips.com:
  - Leave __phys_to_dma(), __dma_to_phys() & pcibus_to_node() in
    arch/mips/pci/pci-ip27.c since the motivation for moving them
    disappeared when the driver stopped being moved to drivers/pci.]
