This interface driver is a helper driver allows other drivers to
have a common interface with the Hyper-V PCI frontend driver.

Altera MSI IP is a soft IP and is only available after
an FPGA image (with design containing it) is programmed.

Make driver modulable to support use case FPGA image is programmed the
after kernel has booted, so that the driver can be loaded upon request.

We have supported per-device dma_map_ops in generic code for a long
time, and this symbol just guards the inclusion of the dma_map_ops
registry used for vmd.  Stop enabling it for anything but vmd.

No change in functionality intended.

The PCI controller in the Marvell Armada 3720 does not implement a
software-accessible root port PCI bridge configuration space. This
causes a number of problems when using PCIe switches or when the Max
Payload size needs to be aligned between the root complex and the
endpoint.

Implementing an emulated root PCI bridge, like is already done in the
pci-mvebu driver for older Marvell platforms allows to solve those
issues, and also to support features such as ASR, PME, VC, HP.

Implement remove() callback function for the Mediatek PCIe controller
driver to add loadable kernel module support.

Save the PCIe's GIC IRQ at probe so that it can be retrieved to
call dispose_irq() to tear down the IRQ upon module removal.
