Subject: [PATCH 11/40] drm/amd/pm/powerplay/hwmgr/ppevvmath: Place variable declaration under same clause as its use

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

 drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/ppevvmath.h: In function ‘fMultiply’:
 drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/ppevvmath.h:336:22: warning: variable ‘Y_LessThanOne’ set but not used [-Wunused-but-set-variable]
 drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/ppevvmath.h:336:7: warning: variable ‘X_LessThanOne’ set but not used [-Wunused-but-set-variable]
