soc/intel/xeon_sp/cpx: add ACPI name for CSTACK

Add ACPI name for CSTACK. The name is PC00 to match with ACPI table
generated.

The PCIe domain has multiple PCIe stacks. devicetree.cb at the moment
does not support multiple PCIe stacks, eg. IIO stacks. For now, assign
the name to PCIe domain. In future, the name needs to be assigned to
CSTACK.
