[PATCH 07/10] drm/tegra: Make syncpoints be per-context

[Mikko Perttunen <mperttunen@xxxxxxxxxx>]

As a preparation for each context potentially being able to have a
separate hardware channel, and thus requiring a separate syncpoint,
move syncpoints to be stored inside each context instead of global
client data.
