More importantly, it's broken, because it'll cause Kconfig to complain
if you enable DRM_I2C_NXP_TDA998X, but have ASoC disabled.
Moreover, if you decide you want the sound and ASoC built as a module,
but want to build in DRM and TDA998x support (so you can get video
output working on boot before initramfs/rootfs), Kconfig may well
complain.

There's no need for these if they remain as the above. Modules can have
both init/exit functions, or neither, and they are still unloadable.
Only modules which provide only an init function get locked in on load.
