[PATCH 09/12] MIPS: BRIDGE: Use !pci_is_root_bus(bus) to check for bus->number > 0

[Joshua Kinard <kumba@xxxxxxxxxx>]

From: Joshua Kinard <kumba@xxxxxxxxxx>

This is a manual cherrypick of commit c7ddc3d137b7 from Alastair
Bridgewater's IP35 tree.  In arch/mips/pci/ops-bridge.c, replace:
    if (bus->number > 0)
        foo();

With:
    if (!pci_is_root_bus(bus))
        foo();
