Introducing a new NUMA affinity, FORM2, requires a new mechanism to switch between affinity modes after CAS. Also, we want FORM2 data structures and functions to be completely separated from the existing FORM1 code, allowing us to avoid adding new code that inherits the existing complexity of FORM1. The idea of switching values used by the write_dt() functions in spapr_numa.c was already introduced in the previous patch, and the same approach will be used when dealing with the FORM1 and FORM2 arrays. We can accomplish that by that by renaming the existing numa_assoc_array to FORM1_assoc_array, which now is used exclusively to handle FORM1 affinity data. A new helper get_associativity() is then introduced to be used by the write_dt() functions to retrieve the current ibm,associativity array of a given node, after considering affinity selection that might have been done during CAS. All code that was using numa_assoc_array now needs to retrieve the array by calling this function. This will allow for an easier plug of FORM2 data later on.
