Subject: drm: rcar-du: Fix display timing controller parameter

From: Koji Matsuoka <[email protected]>

commit 9cdced8a39c04cf798ddb2a27cb5952f7d39f633 upstream.

There is a bug in the setting of the DES (Display Enable Signal) register. This current setting occurs 1 dot left shift. The DES register should be set minus one value about the specifying value with H/W specification. This patch corrects it.
