[PATCH 04/10] drm/ttm: add wait for idle in all drivers bo_move functions

[Christian König]

From: Christian König <christian.koe...@amd.com>

Wait for idle before moving the BO in all drivers implementing
an accelerated move function.

This should keep the current behavior when removing the pre move wait.
