ACPI: HMAT: Remove register of memory node for generic target 

[ Upstream commit 54b9460b0a ]

For generic targets, there's no reason to call
register_memory_node_under_compute_node() with the access levels that are
only visible to HMAT handling code. Only update the attributes and rename
hmat_register_generic_target_initiators() to hmat_update_generic_target().

The original call path ends up triggering register_memory_node_under_compute_node().
Although the access level would be "3" and not impact any current node arrays, it
introduces unwanted data into the numa node access_coordinate array.

Fixes: a3a3e341f1 ("acpi: numa: Add setting of generic port system locality attributes")
