Subject: [PATCH] drm/exynos: remove redundant initialization to variable 'start'

From: Colin Ian King <colin.king@...onical.com>

The variable 'start' is being initialized with a value that is never read
and it is being updated later with a new value.  The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
