tools/testing/cxl: Move cxl_test resources to the top of memory 



A recent QEMU upgrade resulted in collisions between QEMU's chosen
location for PCI MMIO and cxl_test's fake address location for emulated
CXL purposes. This was great for testing resource collisions, but not so
great for continuing to test the nominal cases. Move cxl_test to the
top-of-memory where it is less likely to collide with other resources.
