drm/omap: dss: hdmi5: convert to devm_drm_bridge_alloc() API

Browse Source 
This is the new API for allocating DRM bridges.

Switching from a non-devm to a devm allocation allows removing the kfree()
in the remove function and in the probe error management code, and as a
consequence to simplify the code flow by removing now unnecessary gotos.
