[PATCH] drm/tilcdc: Fix suspend/resume drvdata

[Markus Schneider-Pargmann (TI)]

drvdata contains a pointer to a struct tilcdc_drm_private and not a
pointer to a struct drm_device anymore.

Note that this breaks suspend/resume at the moment, it hangs on
acquiring a mutex.

Interpret drvdata correctly as struct tilcdc_drm_private as is done in
the rest of the driver.
