Apparently the PCIe capability is at address 0x40 in config space of X-Gene
v1 Root Ports.  Add a definition of that and use the generic PCI_EXP_RTCTL
offset into the capability.  No functional change intended.

When platform_get_irq() fails we should propagate the real error value
instead of always returning -EINVAL.
