Input: tizen_bezel: Change event value of the bezel devicesubmit/tizen/20200323.012640accepted/tizen/unified/20200324.101622

Until Tizen 5.0, for bezel input device, its event value was in
between -2 and 2, but value 1. meant starting movement to
counter clockwiseare or clockwise, and value -1, meant moving back
to original position, never used. Change event value of the bezel
device for Tizen 5.5 and later version.

It changes bezel input driver event interface, so user input
framework for bezel input should be also changed.
