maru: rotary: Change event valuesubmit/tizen/20200323.012640accepted/tizen/unified/20200324.101627
Until Tizen 5.0, for detent/bezel input device, its event value
was in between -2 and 2, but value 1, meant starting movement to
counter clockwise or clockwise, and value -1, meant moving back
to original position, never used. Change event value of the
detent/bezel device for Tizen 5.5 and later version.
It changes detent/bezel input driver event interface, so user
input framework for detent/bezel input should be also changed.
