[PATCH] drm/bridge: tc358767: Use devm_clk_get_enabled() helper

[Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>]

The devm_clk_get_enabled() helper:
   - calls devm_clk_get()
   - calls clk_prepare_enable() and registers what is needed in order to
     call clk_disable_unprepare() when needed, as a managed resource.

This simplifies the code and avoids the need of a dedicated function used
with devm_add_action_or_reset().
