drm/tegra: Rename host1x_drm_context to tegra_drm_context
The structure represents a context associated with a particular process that has opened the Tegra DRM device and requested a channel. This is a very DRM-specific notion and has nothing to do with host1x. Rename the structure to more clearly mark the boundaries between the two. Signed-off-by: Thierry Reding <treding@nvidia.com>
