anv: Add an explicit_address parameter to anv_device_alloc_bo

We already have a mechanism for specifying that we want a fixed address
provided by the driver internals.  We're about to let the client start
specifying addresses in some very special scenarios as well so we want
to pass this through to the allocation function.
