size_t is limited to 32-bits and so the gen_pool_alloc() using the size of SZ_64G would map to 0, triggering a low allocation which is not expected. Force the dependency on 64-bit for cxl_test as that is what it was designed for.
This issue was found by build test reports when converting this driver as a proper upstream driver.
