[nrf fromlist] dts: nordic: specify device model of global hsfll clock

Add specific device model for global hsfll clock and update dts tree to use specific model. The clock is not fixed, and configurable at runtime to predefined frequencies specified by the platform. Upstream PR #: 81735 Signed-off-by: Bjarki Arge Andreasen <[email protected]>

+  Nordic Global HSFLL clock.
+
+  The lowest supported clock frequency is the default
+  clock frequency.
+
+  Example:
+
+    global_hsfll: global_hsfll {

+            clocks = <&fll16>;
+            #clock-cells = <0>;
+            supported-clock-frequencies = <64000000
+                                           128000000
+                                           320000000>;
