Switch tests over to the new drmm_connector_hdmi_init() signature, where the vendor, product, supported_formats and max_bpc values previously passed as arguments are now provided through struct drm_connector_hdmi_funcs.
As a consequence, the tests exercising those values can no longer share the static dummy_hdmi_funcs and need a modified copy of their own. Since the connector retains a pointer to it, such a copy must not be placed on the stack, which is gone by the time the DRM-managed actions release the connector. Keep it in struct drm_connector_init_priv instead: it embeds the DRM device and is only freed via managed.final_kfree, i.e. once drm_dev_release() has run all DRM-managed actions, so its lifetime strictly outlives the connector. Note that a kunit_kzalloc() buffer would not be suitable, as KUnit releases its resources in reverse order, hence one allocated by a test would be freed before the DRM device allocated by the suite .init().
