[PATCH] drm/radeon: Remove limitation on clock speeds

Mon Sep 22 21:42:03 PDT 2014
Now that vddci has been fixed for dpm, we can let the GPUs
use their maximum values when not using the reference ones.
Fixes bug 69721: Can't reach maximum memory speed (or core
speed) when using dpm=1 on r600g on cards not sticking to
reference board
Tested on kernel 3.17-rc7 on a cayman gpu.
