[PATCH 2/2] ASoC: Intel: soc-acpi-intel-mtl-match: add missing empty item

[Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx>]

There is no links_num in struct snd_soc_acpi_mach {}, and we test
!link->num_adr as a condition to end the loop in hda_sdw_machine_select().
So an empty item in struct snd_soc_acpi_link_adr array is required.

Fixes: f77ae7fcdc4763 ("ASoC: Intel: soc-acpi-intel-mtl-match: add cs42l43 only support")
