The new audio code fails to build when sounds support is in a loadable
module but the GPU driver is built-in:
x86_64-linux-ld: zynqmp_dp_audio.c:(.text+0x6a8): undefined reference to `devm_snd_soc_register_card'
x86_64-linux-ld: drivers/gpu/drm/xlnx/zynqmp_dp_audio.o:(.rodata+0x1bc): undefined reference to `snd_soc_info_volsw'

Change the Kconfig dependency to disallow the sound support in this
configuration.

Choose this option to enable DisplayPort audio support in the ZynqMP
Thanks, pushing to drm-misc-next.
