drm/radeon/kms: use udelay for short delays

commit 01d4503968f471f876fb44335800d2cf8dc5a2ce upstream.

For usec delays use udelay instead of scheduling, this should
allow reclocking to happen faster. This also was the cause
of reported 33s delays at bootup on certain systems.

fixes: freedesktop.org bug 25506
