The ace2x driver can be build with or without mlink support, but
when SND_SOC_SOF_HDA_MLINK is set to =m and soundwire is built-in,
it fails with a link error:
ld.lld: error: undefined symbol: hdac_bus_eml_sdw_wait_syncpu_unlocked
>>> referenced by intel_ace2x.c
>>> drivers/soundwire/intel_ace2x.o:(intel_link_power_up) in archive vmlinux.a
ld.lld: error: undefined symbol: hdac_bus_eml_sdw_sync_arm_unlocked
>>> referenced by intel_ace2x.c
>>> drivers/soundwire/intel_ace2x.o:(intel_sync_arm) in archive vmlinux.a
Add a Kconfig dependency that prevents that broken configuration but
still allows soundwire to be a loadable module instead.
