ACPI: scan: Extract CSI-2 connection graph from _CRS
Find ACPI CSI-2 resource descriptors defined since ACPI 6.4 (for
CSI-2 and camera configuration) in _CRS for all device objects in
the given scope of the ACPI namespace that have them, identify the
corresponding "remote endpoint" device objects for them and
allocate memory for software nodes needed to create a DT-like data
structure representing the CSI-2 connection graph for drivers.
The code needed to populate these software nodes will be added by
subsequent change sets.
