drm/radeon/dpm: drop clk/voltage dependency filters for CI
Not sure this was ever necessary for CI, was just done to be on the safe side. bug: https://bugs.freedesktop.org/show_bug.cgi?id=69721 Reviewed-by: Alexandre Demers <alexandre.f.demers@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
