drm/tilcdc: Get rid of legacy dpms mechanism

Browse Source 
Get rid of legacy dpms mechanism. This simplifies the code quite a
bit. The old start() and stop() functions become tilcdc_crtc_enable()
and *_disable(). The functions are added with all the necessary
mechanisms from the old dpms function and they are used directly as
the crtc helper enable() and disable() callbacks.
