[ Upstream commit 2cb54788393134d8174ee594002baae3ce52c61e ]
The Lenovo Yoga Tab 3 Pro YT3-X90 x86 tablet, which ships with Android with a custom kernel as factory OS, does not list the used WM5102 codec inside its DSDT.
Workaround this with a new snd_soc_acpi_intel_baytrail_machines[] entry which matches on the SST id instead of the codec id like nocodec does, combined with using a machine_quirk callback which returns NULL on other machines to skip the new entry on other machines.
