Subject: [PATCH] drm/radeon/ci_dpm: Remove redundant initialization of variables hi_sidd, lo_sidd

From: Colin Ian King <[email protected]>

The variables hi_sidd and lo_sidd are being initialized with a values
that are never read, they are being updated later on. The assignments
are redundant and can be removed.
