 ASoC: rsnd: Fix probe failure on HiHope boards due to endpoint parsing 
On the HiHope boards, we have a single port with a single endpoint defined
as below:
....
        rsnd_port: port {
                rsnd_endpoint: endpoint {
                        remote-endpoint = <&dw_hdmi0_snd_in>;

                        dai-format = "i2s";
                        bitclock-master = <&rsnd_endpoint>;
                        frame-master = <&rsnd_endpoint>;

                        playback = <&ssi2>;
                };
        };
....

With commit 547b02f74e ("ASoC: rsnd: enable multi Component support for
Audio Graph Card/Card2"), support for multiple ports was added. This caused
probe failures on HiHope boards, as the endpoint could not be retrieved due
to incorrect device node pointers being used.

This patch fixes the issue by updating the `rsnd_dai_of_node()` and
`rsnd_dai_probe()` functions to use the correct device node pointers based
on the port names ('port' or 'ports'). It ensures that the endpoint is
properly parsed for both single and multi-port configurations, restoring
compatibility with HiHope boards.
