it should be the other way around, this machine driver should have a 
dependency on SPI and select RT5677_SPI?

That said, even with this fix, I still see issues, somehow the 
spi-RT5677AA component does not probe/register, see 
https://github.com/thesofproject/linux/pull/1659

There must be an additional issue with SPI support here.
