The only dependency is on the MT6359 PMIC's audio related IPs and nothing else.

I'd even remove the other select statements for the other codecs, honestly,
as there's no reason why MT8188 wouldn't support a codec or the other, and
there is no reason why that SoC needs exactly those codecs, apart from some
board (Chromebooks) having one, or the other.

Instead of adding a select statement on MT8188_MT6359, adding the TAS2781_I2C
driver as a module in defconfig is a better idea..... at least, IMO.

I agree it doesn't make any huge difference, but I also don't see why users
can't simply enable (y/m) that in the kernel configuration :-)
