ASoC: macaudio: Set long_name during probe()

This prevents filling the long_name from DMI data soon to be provided by
u-boot's SMBIOS support. This is necessary since ALSA ucm uses the long
name to load the ucm config file. The asahi ucm config files are use the
"model" property from devicetree. The DMI information is not always
present and should not be used on these systems.
