cxl/acpi: Ensure ports ready at cxl_acpi_probe() return

In order to ensure root CXL ports are enabled upon cxl_acpi_probe()
when the 'cxl_port' driver is built as a module, arrange for the
module to be pre-loaded or built-in.

The "Fixes:" but no "Cc: stable" on this patch reflects that the issue
is merely by inspection since the bug that triggered the discovery of
this potential problem [1] is fixed by other means. However, a stable
backport should do no harm.

Fixes: 8dd2bc0f ("cxl/mem: Add the cxl_mem driver")
