ACPI: NUMA: Add CXL CFMWS 'nodes' to the possible nodes set
The ACPI CEDT.CFMWS indicates a range of possible address where new CXL
regions can appear. Each range is associated with a QTG id (QoS
Throttling Group id). For each range + QTG pair that is not covered by a proximity
domain in the SRAT, Linux creates a new NUMA node. However, the commit
that added the new ranges missed updating the node_possible mask which
causes memory_group_register() to fail. Add the new nodes to the
nodes_possible mask.
