Arnd Bergmann a1b828f202 soundwire: intel_ace2x: fix SND_SOC_SOF_HDA_MLINK dependency
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.

SoundWire is a 2-Pin interface with data and clock line ratified
by the MIPI Alliance. SoundWire is used for transporting data
typically related to audio functions. SoundWire interface is
optimized to integrate audio devices in mobile or mobile inspired
systems. Say Y to enable this subsystem, N if you do not have such
