This allows the drivers to move a BO to the end of the LRU
without removing and adding it again.

v2: Make it more robust, handle pinned and swapable BOs as well.

If we import a BO with an external reservation object we don't
reserve/unreserve it. So we never add it to the LRU causing a possible
denial of service.

Hardware blocks on the GPU like ACP generate interrupts in
the GPU interrupt controller, but are driven by a separate
driver.  Add an irq domain to the GPU driver so that
blocks like ACP can register a Linux interrupt.

This provides an interface to get access to the base address
of PCI resources (MMIO, DOORBELL, etc.).  Only MMIO and
DOORBELL are implemented right now.  This is necessary to
properly utilize shared drivers on platform devices.  IP
modules can use this interface to get the base address
of the resource and add any additional offset and set the
size when setting up the platform driver(s).
