drm/radeon: gcc fixes for ni dpm
Newer versions of gcc seem to wander off into the weeds when dealing with variable sizes arrays in structs. Rather than indexing the arrays, use pointer arithmetic. See bugs: https://bugs.freedesktop.org/show_bug.cgi?id=66932 https://bugs.freedesktop.org/show_bug.cgi?id=66972 https://bugs.freedesktop.org/show_bug.cgi?id=66945 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
