893ebad99d2603da43ef8a48ec66e113592c9203 pci: program correct bridge limit registers during probe
According to the pci-to-pci bridge specification, memory/io limit
should be the last address of the window, while currently its set to
last + 1. It broke when the memory range was increased and hit 32-bit
limit. The last address in the window is 0xFFFF.FFFF and max-mmio is
0x1.0000.0000, because of the bug 0x0000 got programmed in the memory
limit register. All the mmio reads across the pci-to-pci bridge
started failing during probe.
All pci-bridge-set-[mmio,mem,io]-base sufferred from similar problem.
