drm/bridge: dw-hdmi: handle ELD when DRM_BRIDGE_ATTACH_NO_CONNECTOR
The current ELD handling takes the internal connector ELD buffer and shares it to the I2S and AHB sub-driver. But with DRM_BRIDGE_ATTACH_NO_CONNECTOR, the connector is created elsewhere (or not), and an eventual connector is known only if the bridge chain up to a connector is enabled. The current dw-hdmi code gets the current connector from atomic_enable() so use the already stored connector pointer and replace the buffer pointer with a callback returning the current connector ELD buffer. Since a connector is not always available, either pass an empty ELD to the alsa HDMI driver or don't call snd_pcm_hw_constraint_eld() in AHB driver.
