The next preliminary step to introduce NUMA FORM2 affinity is to make the existing code independent of FORM1 macros and values, i.e. MAX_DISTANCE_REF_POINTS, NUMA_ASSOC_SIZE and VCPU_ASSOC_SIZE. This patch accomplishes that by doing the following: - move the NUMA related macros from spapr.h to spapr_numa.c where they are used. spapr.h gets instead a 'NUMA_NODES_MAX_NUM' macro that is used to refer to the maximum number of NUMA nodes, including GPU nodes, that the machine can support; - MAX_DISTANCE_REF_POINTS and NUMA_ASSOC_SIZE are renamed to FORM1_DIST_REF_POINTS and FORM1_NUMA_ASSOC_SIZE. These FORM1 specific macros are used in FORM1 init functions; - code that uses MAX_DISTANCE_REF_POINTS now retrieves the max_dist_ref_points value using get_max_dist_ref_points(). NUMA_ASSOC_SIZE is replaced by get_numa_assoc_size() and VCPU_ASSOC_SIZE is replaced by get_vcpu_assoc_size(). These functions are used by the generic device tree functions and h_home_node_associativity() and will allow them to switch between FORM1 and FORM2 without changing their core logic.
