Patch

From 39cd26b5d602f57a114def29b8c0931b4069da89 Mon Sep 17 00:00:00 2001
From: Alex Deucher <alexander.deucher@amd.com>
Date: Thu, 15 Jan 2015 10:52:33 -0500
Subject: [PATCH] drm/radeon: use rv515_ring_start on r5xx

At some point these seems to have been lost in favor
of the r300_ring_start function.
