ASoC: apple: mca: Support FEs being clock consumers

Browse source

Support FEs being I2S clock consumers. This does not mean we support
accepting clocks from outside the SoC (although it paves the way for
that support in the future), but it means multiple FEs can attach to one
BE, one being clock producer and the rest clock consumers.

This is useful for grabbing I/V sense data on some machines, since in
such a scenario the format of the sense data on the I2S bus differs
from that of the audio data (the two formats differing in slot width).
With two FEs attached to the bus, we can split the responsibilities and
command different slot widths to the two.
