drm/i915: Make DSB lower level
We could have many different uses for the DSB(s) during a
single commit, so the current approach of passing the whole
crtc_state to the DSB functions is far too high level. Lower
the abstraction a little bit so each DSB user can decide where
to stick the command buffer/etc.
v2: Document the intel_dsb_prepare() return value (Ankit)
