drm/amd/display/dc/dce/dce_dmcu: Move 'abm_gain_stepsize' to only source file it's used in

Browse Source 
And only declare it if it's to be used.

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_dmcu.h:320:23: warning: ‘abm_gain_stepsize’ defined but not used [-Wunused-const-variable=]
