soc/intel/xeon_sp/spr: Create CXL ACPI resources only for
CXL IIO stacks

When an IIO stack is connected with CXL cards, its bus range
will be divided by a PCI host bridge object and a CXL host
bridge object, otherwise, all its range will be owned by the
PCI host bridge object. Accordingly, CXL ACPI resources should
be only created when the IIO stack is connected with a CXL
card.
