There is a single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports. This MSI block supports 2048 MSI termination ports coalesced into 16 physical HW IRQ lines and shared across all 5 PCIe ports. As there are only 16 HW IRQs to serve 2048 MSI vectors, to support set_affinity correctly for each MSI vectors, the 16 HW IRQs are statically allocated to 8 X-Gene v1 cores (2 HW IRQs for each cores). To steer MSI interrupt to target CPU, MSI vector is moved around these HW IRQs lines. With this approach, the total MSI vectors this driver supports is reduced to 256.

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.

The driver uses only an empty ARM pci_sys_data struct and does not use pci_common_init_dev init function. The old host code will be removed in a subsequent commit when Versatile is completely converted to DT. I've tested this on QEMU with the sym53c8xx driver in both i/o and memory mapped modes.

Main differences are: 1. No ATU support 2. Legacy and MSI IRQ functions are implemented in application register space 3. MSI interrupts are multiplexed over 8 IRQ lines to the Host side. All of the application register space handing code is organized into pci-keystone-dw.c and the functions are called from pci-keystone.c to implement PCI controller driver. Also add necessary DT documentation and update the MAINTAINERS file for the driver.
