From: Richard Gong <richard.gong@xxxxxxxxx>
The reconfiguration mode is pre-set by driver as the full reconfiguration.
As a result, user have to change code and recompile the drivers if he or
she wants to perform a partial reconfiguration. Removing the pre-set
reconfiguration condition so that user can select full or partial
reconfiguration via overlay device tree without recompiling the drivers.
Also add an error message if the configuration request is failure.
