[PATCH 7/9] of: make OF_DYNAMIC selectable independently of OF_UNITTEST

The writable status sysfs file enabled by the 'dynamic' DT property
requires CONFIG_OF_DYNAMIC to be useful, but that shouldn't require
dragging in CONFIG_OF_UNITTEST as well.

 	  On some platforms, the device tree can be manipulated at runtime.

+	  "okay" and "reserved" via sysfs.  This can also be enabled to
+	  increase test coverage with CONFIG_OF_UNITTEST if desired.
