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

...

...

Add a Kconfig dependency that prevents that broken configuration but still allows soundwire to be a loadable module instead.
