ASoC: SOF: imx: Add mach entry to select cs42888 topology

After commit 2b9cdef ("ASoC: SOF: imx: Add devicetree support
to select topologies") we select topology to be used by the board
compatible string in the dts.

Now that we have a way to know when the baseboard is installed, use
the board compatible and select proper topology files when the cs42888
Audio IO card is used.
