drm/vc4: use new debugfs device-centered functions
Currently, vc4 has its own debugfs infrastructure that adds the debugfs
files on drm_dev_register(). With the introduction of the new debugfs,
functions, replace the vc4 debugfs structure with the DRM debugfs
device-centered function, drm_debugfs_add_file().
Moreover, remove the explicit error handling of debugfs related functions,
considering that the only failure mode is -ENOMEM and also that error
handling is not recommended for debugfs functions, as pointed out in [1].
