Ho-Ren (Jack) Chuang 823430c8e9 memory tier: consolidate the initialization of memory tiers 
The current memory tier initialization process is distributed across two
different functions, memory_tier_init() and memory_tier_late_init().  This
design is hard to maintain.  Thus, this patch is proposed to reduce the
possible code paths by consolidating different initialization patches into
one.

The earlier discussion with Jonathan and Ying is listed here:
https://lore.kernel.org/lkml/20240405150244.00004b49@Huawei.com/

If we want to put these two initializations together, they must be placed
together in the later function.  Because only at that time, the HMAT
information will be ready, adist between nodes can be calculated, and
memory tiering can be established based on the adist.  So we position the
initialization at memory_tier_init() to the memory_tier_late_init() call. 
Moreover, it's natural to keep memory_tier initialization in drivers at
device_initcall() level.

If we simply move the set_node_memory_tier() from memory_tier_init() to
late_initcall(), it will result in HMAT not registering the
mt_adistance_algorithm callback function, because set_node_memory_tier()
is not performed during the memory tiering initialization phase, leading
to a lack of correct default_dram information.

Therefore, we introduced a nodemask to pass the information of the default
DRAM nodes.  The reason for not choosing to reuse default_dram_type->nodes
is that it is not clean enough.  So in the end, we use a __initdata
variable, which is a variable that is released once initialization is
complete, including both CPU and memory nodes for HMAT to iterate through.
