Update sound card label on rk3588-rock-5b
The audio-graph-card driver uses the 'label' property to register the sound card in the system, but the currently assigned string is too generic and cannot be supported by alsa-project/alsa-ucm-conf:
card 0: Analog [Analog]
Use the more specific naming "rk3588-es8316", which is still generic enough to be shared with other compatible boards, e.g. Rock 5A. The audio card will be listed as:
card 0: rk3588es8316 [rk3588-es8316]
