On arm64 PCI config memory is expected to be mapped with a non-posted
device type. To handle this use the new bus_map_resource support in
arm64 to map memory with the new VM_MEMATTR_DEVICE_NP attribute. This
memory has already been allocated and activated, it just needs to be
mapped.

Things changed:
* do not allocate 4GB of SLI space, because it's the waste of
system resources. Allocate only small portions when needed.
* provide own implementation of activate_resource which performs
address translation between PCI bus and host PA address space.
This is temporary solution, should be replaced by bus_map_resource
once implemented.

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.
