The resource list is only used in the setup process and was never freed.
pci_add_resource() allocates a memory area to store the list item.
Fix the memory leak.

The struct iproc_pcie.resources member was pointing to a stack variable and
is invalid after the registration function returned.
Remove this pointer and add a parameter to the function.

This driver adds support for the PCIe 2.0 controller found on the BCMA bus.
This controller can be found on (mostly) all Broadcom BCM470X / BCM5301X
ARM SoCs.
The driver found in the Broadcom SDK does some more stuff, like setting up
some DMA memory areas, chaining MPS and MRRS to 512 and also some PHY
changes like "improving" the PCIe jitter and doing some special
initialization for the 3rd PCIe port.
This was tested on a bcm4708 board with 2 PCIe ports and wireless cards
connected to them.
PCI_DOMAINS is needed by this driver, because normally there is more than
one PCIe controller and without PCI_DOMAINS only the first controller gets
registered. This controller gets 6 IRQs; the last one is trigged by all
IRQ events.
