Since the ilm memory region is not part of the MT7986 RAM SoC, move ilm
in a deidicated syscon node.

+description:
+  The MediaTek wo-ilm (Information Lifecycle Management) provides a configuration
+  interface for WiFi critical data used by WED WO firmware. WED WO controller is
+  used to perform offload rx packet processing (e.g. 802.11 aggregation packet
+  reordering or rx header translation) on MT7986 soc.
