[PATCH v2] drm/tilcdc: add missing clk_put in tilcdc_unload()

[Julien CHAUVEAU]

We need to call clk_put on display clock, in the same way as functional clock.
Also remove the check for priv->clk, since clk_put() is safe against NULL pointers.

Changes since v1:
- remove the check for priv->clk, as suggested by Felipe Balbi
