[PATCH 3/4] drm/msm: Use msm_gpu_state_bo for ringbuffer data

[Sharat Masetty <smasetty-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

The ring substructure in msm_gpu_state is an extension of
msm_gpu_state_bo, so this patch changes the ring structure
to reuse the msm_gpu_state_bo as a base class, instead of
redefining the required variables.
