Dan Williams 8c9a1ec39c cxl/acpi: Ensure ports ready at cxl_acpi_probe() return
[ Upstream commit 48f62d38a07d464a499fa834638afcfd2b68f852 ]

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: 8dd2bc0f8e02 ("cxl/mem: Add the cxl_mem driver")
